PREFACE. This work professes to contain little more than a truthful record of experience and an endeavour to view that experience in the light of scientific research. Though I have cast it in the form of a trea- tise on nervous disorders, I regard it, of course, as a mere and very imperfect contribution to the literature of so great a subject. I have only touched on those points which seemed to me to have most bearing on practice, but have endeavored as far as possible to indi- cate general principles both in pathology and treatment. I am not without hope that the reviewing of a number of cognate affections may be of advantage to the reader, as showing how close a family resemblance prevails among them, and how the phenomena of one often elucidate those of another disorder. I have necessarily been led to set much value on the results of treatment as indications of the essential nature of disease, in which I am supported by no less a name than Gooch, and this will explain why 1 have recorded few cases except those in which some definite conclusion can be drawn from the actions of remedies. Having myself generally derived most profit from the records of cases, I have used this method of illustra- tion freely, and I trust not unprofitably. There is this value in authentic histories of disease that they represent actual occurrences, and are always available for any future inquirer as evidence of the writer's views, which can hardly be said of abstract descriptions. I do not think it so necessary, as some consider it, to be accurately acquainted with the natural history of disease, for the reason that I believe it impossible in most cases to ascertain it. The attempt recently made by Flint to determine the duration of acute rheuma- tism, no real treatment being adopted, gives in thirteen cases the sufficiently wide variation of from twelve to fifty-six days. I believe with most diseases except the exanthemata it would be nearly the same. In fact I am more and more convinced that we ought not to VI PREFACE. think of diseases as uniform entities, but as very varying and incon- stant pathological conditions. The points which I would indicate as most worthy of attention are the recognition of primary paresis of nervous centres, and its distinction from reflex paralysis, the numerous illustrations of vaso- motor nerve disorder, the theory of inhibitory action, the remarkable afiinity between paralysis, spasm, anassthesia, and neuralgia, the different quality of nervous disorder apparently of the same kind in different instances, the intimate relation of neuralgia in most instances to debility, and the importance of an accurate adjustment of reme- dies to each individual case. While I fully agree with my master, Arnold, on having an un- feigned respect for all kinds of work, I yet think that we have clear indications at the present day what kind of work is most needed, and most likely to bear fruit. While duly estimating morbid ana- tomy and minute physical diagnosis, I cannot but reiterate the wish I have several years ago expressed, that we were more earnest in inquiring into the working of our means of cure, and gaining a more thorough mastery over them. Some united mode of action might surely be devised, I care little about the particular plan, which might in the course of years give us much more certain knowledge about many things in therapeutics than we at present possess. What is the real value of colchicum in gouty disease ? Is digitalis to be specially relied on as a safe stimulant to a weak and failing heart ? Have mercury and antimony a positive control over sthenic inflam- matory action, or have they none ? Should the treatment of acute disease differ materially in town and country folk ? What is the real action of opium ? These and such questions as these I would fain have answered as the profession could answer them if the means at their disposal were effectually employed. I must not conclude without expressing my thanks to many gen- tlemen who have worked with me as clinical assistants during the past thirteen years at St. Mary's, and whose help has often aided me very greatly in studying the cases which have come before me. 49 Green Street, Park Lane.

Of all the parts which go to make up the wonderful whole of the human body, there is none to which a deeper and mOre mysterious '" interest is attached than to the nervous system. By this we think, and move, and have our conscious being ; in this, if anywhere, inhabits our " divinae particula aurse;" by this we are linked with the outer world, and are capable of afiecting and being again affec- ted by the persons and things around us. By this, our immaterial acts upon and sways our material part ; and by the higher develop- ment of this, and its capability for higher actions, man is especially distinguished from the lower creation. All the passions and emo- tions, all the intellectual efforts, all the perceptions and recollections^ operate through and on this system. If this be so, is it any wonder that exhaustion should frequently befall this delicate and complex machinery, or that its disorders should be amongst the most fre- quent that our fallen nature is doomed to bear ? Even under favourable circumstances, the nervous system must often be hardly taxed : how much more, then, will this be the case when sorrow, toil, and anxiety predominate in the lot assigned? It is difficult to form a decided opinion on the matter; but there seems, I think, reason to entertain the belief that failure of nervous power is much more characteristic of disease of the present day, than of that which prevailed thirty years ago. For this there may be various causes : the greater confinement of large numbers of the population within doors, and often in unhealthy rooms or workshops ; the harder struggle to be maintained in the battle of life, the greater amount of the commoda vitce — may all tend to increase the suscepti- bility of the nervous system, and to impair its resisting power. Further, in the two following instances we have, it seems to me, considerable evidence of the altered character of morbid action, de- pending, in all probability, on still more general causes than those just mentioned. (1). Sir Ranald Martin informs me, that whereas invalids returning from India used to take leave of their agues when 2 18 INTRODUCTORY. they arrived in this country, this is no longer the case, relapses being of frequent occurrence. Practitioners of long experience, also, tell us that aguish disorder prevails of late years in places where it was previously unknown, without there being any change in the state of the soil to account for it. (2). There seems no question that puerperal fever is a disease of very different character in differ- ent epidemics. As Dr. Ferguson writes, "under this test," viz., of therapeutic action, " Gooch discovered that puerperal fevers were many, requiring various modes of treatment." I believe this statement cannot be denied ; and if not, it seems a legitimate infer- ence that other diseases may vary also at different times. I may add that my own experience certainly indicates that cholera has a modifying influence on disease. I have not met with nearly so many peculiar neuroses of depression the last few years, as I did for three or four after the last epidemic. Dr. Prout gives testimony to the same effect, v. p. 67. However the exact truth may be, whether the type of disease is altered or not, I hold it to be abundantly clear that the great majority of disorders we have to treat at the present time show more or less marked indications of failure of nervous power ; and I believe it to be a matter of great practical moment to keep this steadily in view. While, however, believing this, I also think that our current pictures of disease are taken far too exclusively from the sick field of large towns ; and I am much inclined to think that if our rural brethren wrote as much as their urban fellows do, they would give a somewhat different account. The course I propose to pursue is, first, to consider the behaviour of the nerves and nervous centres in certain well-marked simple morbid states, and subsequently to notice the more important features of several classic diseases, and of some other less commonly recognized disorders. I do not intend to deal with the results of manifest organic lesion, but to confine my attention chiefly to such disorders as are termed functional. It seems to me a vain dispute, whether in strict accuracy there are, or are not, any such disorders. The probability is that there are not — that in all morbid action the cells and the fibres of the organs undergo some molecular change from their perfectly normal condition. It is, however, perfectly certain that there are very grave disorders in which the most care- ful scrutiny fails to detect any actual change, in which complete recovery is perfectly possible, and in which the " juvantia" are such as operate more in modifying the power of the organs than their texture. To take an example : a man may have paralysis of some muscle or group of muscles which yields to the use of strychnia or galvanism. Now, these agents can scarcely be thought to act other- wise than by exciting and increasing the vital power of the affected nerve or nervous centre; or, to put it shortly, as nerve tonics. Cod-liver oil, iron, and phosphorus might be given without effecting the same beneficial change — at least, as speedily, because they are I^^TRODUCTORY. 19 rather analeptics than tonics. They may improve the nutrition of the nervous tissue, but they do not directly arouse it. Now, between such a case of functional paralysis as we have supposed, and paralysis from organic lesion, there is a wide interval. Strych- nia and galvanism will, in all probability, make the latter worse ; certainly, will not cure it. Something more is needed in this case than to arouse defective nervous energy. Between the typical cases which we have taken of functional and organic disease, there inter- vene numerous instances of more or less mixed character. Inflam- matory disease is from one point of view organic, from another functional. It commences essentially as the latter, it ends as the former. The arrangement I shall adopt is merely topographical, but will, I hope, be found practically convenient. Commencing with the encephalon, including the cerebral hemispheres, mesocephale, cere- bellum, and medulla oblongata, we shall proceed to the spinal cord, and thence to the several nerves or nervous districts, which are found by experience to be most prone to disorder. Under the term cerebral hemispheres is comprised all the convoluted gray exterior of the brain, with its basal ganglia, the corpora striata and thalami optici, and the various longitudinal and transverse comni[^sural fibres. The functions of these parts are eminently mental : they^minister to conscious sensation, memory, reflection, judgment, and volition. Their structure is essentially similar to that of other nervous centres, but has this peculiarity — that the gray matter contains a very con- siderable quantity of loose granular material, and is by no means chiefly made up of nervous cells. This seems to have relation to the rapid nutritional change required by the active function of the tissue. The perfect cell indicates a greater degree of permanency, and slower change than the nucleus with diffused granular material. The very copious supply of blood sent to the hemispheres is also in harmony with this view. The cerebellum is probably concerned in regulating the motor nervous actions, and is, perhaps, the special seat of the muscular sense. The mesocephale is connected with the two chief nerves of special sense, and is, we know from experiment, capable of producing general convulsions when directly irritated. The medulla oblongata is the chief centre of the respiratory nervous actions, and is capable of influencing very materially the cardiac movements : with it are connected all the cranial nerves from the sixth to the ninth. The spinal cord constitutes by its gray matter an independent centre for the nerves which are implanted in it, but is naturally associated by its longitudinal commissural fibres with the superior nervous centres in sensation and volition. The cervi- cal and upper dorsal regions of the cord constitute, according to Bezold, a special motor centre to the heart, furnishing three-fourths of its entire propulsive force. The sympathetic is partly an inde- pendent system, partly an offset from the cerebro-spinal ; as, indeed, its anatomy indicates. 20 GENERAL PATHOLOGY. CHAPTER II. GENERAL PATHOLOGY. Before entering on the special study of disease, it seems desirable to allude briefly to some well-established points in neuro-physiology and pathology, and to discuss, in a general manner, some questions which are as yet unsolved. The subjects thus elucidated will be convenient for future reference. (I.) It is certain that the nervous cords, whether motor or sensory, in the whole of their course, from their origin to their peripheral distribution, allow of no communication of the active state from one fibre to another. A single point of the skin when touched is dis- tinguished by the sensorium from the adjacent, the size of the district thus represented in the brain varying inversely with the abundance of nervous s\^ply ; and a single muscle can be put into action with- out exciting others receiving nerves from the same trunk. It is remarkable how the stimulus of the will can be limited to certain groups of nerve-cells at some distance from each other without affecting others in close proximity. We can call into action the triceps extensor cubiti without moving any other muscle. Yet, the filaments animating this nerve must come, in all probability, from various points of the spinal cord between the fifth cervical and first dorsal nerves; and the cells of these points alone are excited, while others close by remain inactive. (II.) While the above, which Romberg terras the law of isolated conduction, holds in the peripheral tracts, we find another of a very different kind to come into play in the nervous centres. In them we have — (a.) What is termed excito-motory or reflex action, viz., an impression from a centripetal nerve, producing an active state of a motor through the intermedium of certain multipolar cells. Sensa- tion almost invariably ensues at the same time, but is not an essential part of the chain of actions. Volition is quite unconcerned in the act, and is often quite incapable of controlling it. (b.) The impres- sion arriving at the centre is communicated, not to a motor, but to a sensory nerve-root, perhaps to several adjacent, or to another more remote. In this way, sensations are produced which continue as long as the original impression is maintained by its existing cause. In certain states of great excitability of the nervous centres, the range over which the primary stimulus may extend, especially in the case where motor nerves are aff'ected, is very considerable. In dealing with neuralgic disorders, this point, viz., the irradiation, as it is called, of sensation, is of capital importance, and may often lead GENERAL PATHOLOGY. 21 to the discovery of the cause of suffering, which would otherwise have remained quite obscure. Pflliger lays down the following laws: (1.) That when reflex action occurs on one side, it is always on that where the sensitive nerve has been excited ; and if it occurs on both sides, it is strongest on the side stimulated. (2.) When reflex action occurs on both sides from excitation of one, it affects parts symmetrically situated. (3.) Reflex excitation in cerebral nerves extends from before back- wards, in spinal nerves from behind forwards. (Vide Brit, cf- For. Med.-Ghir. Rev., Jan. 1864, p. 9.) (III.) The law of eccentric phenomena affirms that every sensation, as it becomes perceptible to consciousness, is referred to the periphery of a sensitive fibre, no matter at what part of the whole length of the fibre the impression is made. This law is to a certain extent true, but admits, as I shall point out subsequently, of numerous exceptions. (IV.) It seems to be well ascertained that an unfelt irritation may give rise to very various morbid phenomena affecting both the motor and sensory nervous organs. Dr. Brown-Sequard maintains that various forms of insanity, of vertigo, epilepsy, of hallucinations and illusions, and also extasis, catalepsy, hysteria, chorea, hydro- phobia, tetanus, &c., may be due to irritations starting from a cen- tripetal nerve, and frequently slightly felt, or unfelt, and that the suppression of these irritations may promptly cure the patient. Graves records a case (Vide Clin. Med.., p. 244) where an extremely severe cough, which had resisted all treatment directed to relieve, bronchitis, ceased at once on the expulsion of a mass of tapeworm by a dose of turpentine. It does not appear that any symptoms had existed in this case to announce the presence of the intestinal parasite. Perhaps the following instance is still more proving, inasmuch as the seat of the irritation was in a much more sensitive part. A married lady had suffered for a considerable time from a spasmodic pain in the womb, which ceased completely on the extraction of a tooth that had not caused any material annoyance. (V.) Attention has lately been directed by Pflliger and Lister to certain nerve phenomena, which the former terms inhibitory [hem- mungs), and supposes to belong to a certain set or system of nerve- fibres whose sole function is to arrest or diminish action. Lister, on the contrary, concludes, from his inquiries,^ " that one and the same afferent nerve may, according as it is operating mildly or energetically, either exalt or depress the functions of the nervous centre on which it acts. It is, I believe (he says), upon this that all inhibitory influence depends ; and I suspect that the principle ■will be found to admit of a very general application in physiology." The following are instances of inhibitory action : The poles of a galvanic apparatus being fixed to the spinous processes of the ninth ' Proceedings of the Royal Society, No. 32, p. 367. 22 GENERAL PATHOLOGY. and twelfth dorsal vertebrse of a rabbit, currents were passed through the spine (of course, affecting the cord), with the effect of inducing '•complete relaxation and quiescence of the small intestines, which had been previously in considerable movement, while the muscles of the limbs were thrown into spasmodic action ; but on the dis- continuance of the galvanism the previous intestinal motion re- turned." Weaker currents were then passed, and markedly in- creased the action of the intestines in every instance during the first twenty-five minutes. In the next half-hour the increase of action from the galvanism though still distinct, was less strongly marked, and at the end of that period, with stronger currents, the inhibitory influence was also found to be much less complete than before, indicating that the parts of the nervous apparatus concerned were in a less active condition, no doubt in consequence of exhaus- tion. Increased movements of the intestine were produced by direct irritation of the cord with a fine needle. It was very worthy of remark, that violent struggling of the rabbit, when the intestines were in pretty free movement, was followed by absolute and uni- versal quiescence of those organs for several seconds. This showed that an inhibitory action was capable of being produced naturally as well as artificially. The recent observations of Hufschmidt and Moleschott,^ as to the effect of mechanical irritation of the medulla oblongata and spinal cord on the frequency of the pulse, accord very much with those of Lister. They found^ that slight electric irritation of the medulla oblongata augmented, while more powerful .diminished the frequency of the heart's action, or even arrested it. (2). Powerful mechanical irritation ofthe medulla oblongata diminished the frequency of the heart's action. (3). Slight irritation of the spinal cord increases, powerful irritation diminishes the frequency of the heart's action. Weber and Bernard^ had long before demon- strated the possibility of arresting or slowing the action of the heart by galvanizing the medulla oblongata or the pneumogastric nerve. In a paper on Inhibitory Influence^ I have endeavoured to show that pathological phenomena are not infrecjuent which seem to be of this nature. I modify, however, the statement of Mr. Lister, so far as to believe that it is not the energetic operation of an afferent nerve that causes inhibitory action, but its being injuriously affected by some impression made upon it. The enfeebled state of the nerve itself, or of the centre to which it proceeds, or the severity or malignity of the impression, may give rise to the peculiar effect. The following instances may be cited as fair examples : 0. J.," ast. 37, got a whitlow on the last phalanx of left thumb ; the lymphatics were inflamed, and the axillary glands swollen ; the whole arm was 1 Moleschott's Untersuch, vol. viii. part 6, 1862.

GENERAL PATHOLOGY. 23 very painful. While the limb was in this state, one morning he found that he saw double, and had a squint in the left eye. At the Ophthalmic Hospital, it was found that the external rectus muscle was completely paralyzed, and he had circuraorbital pain. It was supposed that there was periosteal inflammation about the orbit, and pot. iodid. was given ; the whitlow was poulticed, and the arm fomented. After a month of this treatment, there was no improve- ment of the eye, but the arm inflammation had quite subsided. A piece of dead bone was now removed from the seat of the whitlow ; soon after which the squint disappeared, as well as the pain in the arm and about the orbit. The external rectus had quite recovered its power. In this instance, pain in sensory nerves about the orbit and paralysis of a single motor nerve were co-results of the morbid impression conveyed from the diseased finger to the centre. Dr. Watson refers to the production of amaurosis without visible change in the eye, in consequence, apparently, of irritation of the dental nerves, the blindness ceasing after the extraction of some teeth which had grown irregularly.^ He quotes from Mr. Lawrence an interesting case, in which the extraction of a carious tooth, with a splinter of wood projecting from one of its fangs, procured the restoration of the sight of the eye of the same side, which had been entirely lost for thirteen months. In such cases, the paralysis of the retina or of the optic tubercles may fairly be designated inhibi- tory. Two cases of amaurosis and one of ptosis are recorded by Mr. Hancock^ as cured by the removal of decayed or overcrowded teeth. ]Mr. Fleischmann^ gives a case in which an obstinate muco-purulent discharge from the right nostril, which had resisted other treatments, yielded to extraction of the right upper canine. Plucking the large vibrissa at the entrance of the nostrils will, at least in some persons, cause a notable secretion of mucus, evidently dependent on the pain excited. Some while ago, I had a gentleman under my care with acute rosacea of the face and head, and chronic corneitis, with vascular development on the cornea. I applied on one occasion some liq. plumbi diacet., diluted with an equal amount of water, to the upper lids (everted), which I found very red. This caused ex- cessive irritation ; the eyes became greatly congested, watered, extremely, and were very painful ; while the skin of the face, the nose especially, became of a deep red, and all the vessels of the face much congested. There was extreme photophobia. It was half an hour before the hypersemia began to subside. The irrita- tion in this case evidently was reflected from the branches of the first division of the fifth nerve supplying the lids, on to the vaso- motor nerves of the arteries, supplying the skin of the face, which, in consequence of the morbid impression, became dilated — not con- tracted, as they normally should, according to the law of reflex ' Watson's Lectures, voL i. p. 336. 2 Lancet, January 22, 1859. 3 British Medical Journal, April 9, 1859. 24 GENERAL PATHOLOGY. action. This was a marked example of inhibitory action. Dr. Brinton informs me that he has long held and taught a view almost identical with the above, under the name of "reflex relaxation." The pathology of these cases is, no doubt, the same ; a nerve of special sense, a musculo-motor or a vaso-motor being paralyzed according to the direction which the irritation happens to take. To the same class belong, I think, instances of paralysis produced by exposure to cold and wet, though the paralysis often continues long after the morbid impression has ceased. In Mr, Hancock's com- munication, a case of lockjaw and of extreme wryneck are men- tioned as having been cured by removal of dental irritation. This shows that it depends very much on the condition of the nervous centre which is affected, what the result of a nervous stimulus shall be, whether paralyzing or exciting. So, in some persons opium causes marked powerlessness (a degree of paralysis) ; in others it tones and prevents fatigue. The only objection which can be made, I conceive, to the above evidence is, that in the instances cited the paralysis depended, not on a direct morbid influence exerted on the tissue of the nervous centrCjbutonansemiaof the part, producedby the reflection of the origi- nal irritation on the vaso-motor nerves supplying its arteries. This is what Dr. Brovvn-Sequard supposes to occur in reflex paralysis — a form which appears to me to be similar to inhibitory. In reflex paralysis, the loss of motor power appears to depend on an actually existing irritation, with which it increases or diminishes, and with the removal of which it ceases. This is evidently almost identical with what we have described above. The only diff"erence is, that in some instances of inhibitory action the paretic state of the centre persists for an indefinite time after the cessation of the cause which has morbidly aS'ected it. The grounds which lead me to believe that Brown-Sequard's view is incorrect are — (1st). It is difficult to suppose that a spasm of reflex origin should be limited to such a very small extent of vessels as would be involved in some instances, e g., palsy of one sixth nerve, ptosis of one eye. (2d). It is almost impossible to believe that a contraction of vessels should be so per- .sistent as the hypothesis requires. Can we suppose, in the case of amaurosis above cited, that the arteria centralis retinae was spas- modiciilly occluded for thirteen months? (3d). It has been found by Gull that irritation of the renal nerves does not cause contraction of the vessels of the spinal cord, nor paralysis of the lower limbs, as Brown-Sequard stated in explanation of the paraplegia from renal disease. (4th). In some cases of paralysis from exposure to cold and wet — v. one related by Dr, Copland {Diet, of Pract. Med., art. Paralysis, 76), the paralysis continues long after the exciting cause has ceased, and is removed by stimuli applied to the sensory cutane- ous surface. Here the paralysis must be non-organic ; and yet it can scarcely be supposed to depend on anaemia of the centres result- ing from arterial spasm. On the other hand, it is intelligible that GENERAL PATHOLOGY. 25 the nerve- cells might be thrown into a state of enfeebled action by the cold, &c., from which they could not easily recover. These cases, though not typically inhibitory, seem to me very illustrative of the nature of the morbid action. (VI.) It is, I think, a matter of certainty, that a nervous centre may be more or less completely paralyzed without having undergone organic change, in consequence of some enfeebling morbid influence, as the influenzal or malarious miasms, &c. Dr. GulP has published a most interesting instance of complete paraplegia induced by sexual excess, in which nothing abnormal could be detected in the cord even by careful microscopy. This was paralysis from simple exhaustion. Such paralysis may be distinguished as simple or neurolytic. I think it is certain that this does not depend on local anaemia ; which adds to the probability that inhibitory paralj'^sis does not either. (VII.) Anatomically regarded, it is very remarkable how closely the different nervous centres, or parts of a nervous centre, are con- nected by commissural fibres ; and from a pathological point of view, the same connection is often very manifest. The general exhaustion induced by excess in venery, the reproduction of neuralgia in weakly persons by bodily exercise, the effect of muscular exertion in pro- ducing drowsiness, are examples which show how excessive con- sumption of the nerve-force in one part weakens it also in others : and \his can only be adequately explained by the intimate commis- sural connection between the various centres. Tetanus is a good in- stance of the diff'usion of a state of excitement from one part of the cord throughout its whole extent. (VIII.),;,The remarkable influence of the nervous system over the bloodvessels requires some particular notice. Our knowledge on this head has been chiefly the result of Bernard's labours; and it is difficult to overestimate the importance of the study of these phe- nomena to every physician who desires either to comprehend aright the varying and manifold phases of disease, or to attempt the control of morbid actions by remedies in a rational and satisfactory manner. It is well known that in paralysis from disease of the brain or spinal cord, the temperature of the paralyzed parts, as a rule, is lowered. This was found to occur when the anterior or posterior roots of the spinal nerves, or the root of the fifth pair, or that of the facial, were divided. The loss was not very considerable, varying from about 3° to 7° F. When the sympathetic nerve in the neck was divided, or the superior cervical ganglion extirpated, the following phenomena were observed: The temperature of the operated side increased rapidly, and in a quarter of an hour had risen 11° F. ; the arteries and small vessels dilated, and became much more full of blood than those of the opposite side; the pupil contracted, as well as the pal- pebral opening, while the globe of the eye appeared depressed in the orbit. The hypersemia, which is the immediate result of the 1 Guy's Hospital Pieports, 1858, Case xvii. 26 GENERAL PATHOLOGY. operation, subsides considerably in a day or two; but the elevation of the temperature is much more persistent, lasting in rabbits 16 to 18 days ; in dogs 6 weeks to 2 months. Not only the superficial parts, but the deep-seated, and even the blood returning by the jugular vein can be shown to be hotter than the corresponding parts of the healthy side, or than they themslves were previously. It is an important circumstance, observed by Bernard andBrown-Sequard, that the temperature on the sound side falls below its previous figure, the difference in one experiment amounting to 5|-° F. The pheno- mena now described are more prominently marked in healthy and vigorous animals than in those that are weakly, and in those that are digesting food than in those that are fasting. When an animal whose cervical sympathetic has been divided on one side is exposed to a temperature above that of its own body, the side where the nerve is entire gains heat, while the other remains almost unchanged, and, before long, no difference can be detected between them. On the other hand, when an animal similarly circumstanced is placed in a medium considerably colder than its own body, the difference be- tween the normal and the operated side becomes more prominently marked. The former loses heat much faster than the latter, and the thermometer shows it may become as much as 21° F. colder than its fellow. If the upper end of the divided sympathetic is gal- vanized, all the effects produced by the previous operation disappear, and are replaced by their converse. The pupil dilates, as well as the palpebral opening, and the eyeball projects from the orbit. Instead of being active, the circulation becomes weak; the conjunc- tivae, nostrils, and ears, which were red, become pale. Th^ tempera- ture falls below the normal figure, while, curiously enough, that of the opposite side increases notably. According to Brown-Sdquard, the effects produced by a transverse lateral section of the semi-cord in the dorsal region, on the posterior limb of the same side, are exactly similar to those we have been considering. The condition also of the opposite sides in both cases is quite similar; "both receive less blood than usual, their temperature diminishes, their nutrition is less active, and their vital properties also diminish." By recent investigations, Bernard has found that there are two sets of nerves in the cervical sympathetic — one occulo-pupillary, arising in the dog from the anterior roots of the two first dorsal; and the other vascular and calorific, arising from the sympathetic ganglia. He also states that division of the anterior and posterior roots of the nerves proceeding to the posterior extremity in dogs causes paralysis of motion and sensation, but no change of temperature or vascularity. Division of the sciatic nerve, however, raises the temper- ature 6° to 8° C. (11° to 14° F.), and increases the vascularity. Division of the sympathetic nerves has the same effect, but causes no paralysis. Bernard's observations thus go to attribute more importance to the proper fibres of the sympathetic system than to those wiiich it receives from the spinal nerve in controlling the GENERAL PATHOLOGY. 27 local circulation. They demonstrate, certainly, the partial inde- pendence of the sympathetic system. Bernard remarks that though he has watched for a length of time animals who had undergone division of the cervical sympathetic, he has never seen any oedema or inflammatory action supervene in the abnormally hot parts so long as the animals continued in good health ; but if they fell sick, either spontaneously or from the effects of other operations, the mucous membranes of the eye and nose on the operated side only became very red, swelled, and poured out purulent matter abund- antly. If the animal's health improved, these inflammatory phe- nomena ceased. This highly important observation I can quite confirm from my own experience. A cat on which I operated had severe purulent ophthalmia of the left eye for five or six days ; after which it spontaneously declined. Sixteen days after the operation, the left ear was 15° F. hotter than the right. She had been de- bilitated by an unsuccessful attempt to divide the renal nerves on one side. The cause of the elevated temperature of the parts lying in the range of the divided sympathetic is attributed by Brown- S^quard and Waller to the increased afflux of blood to the local hypergemia. Bernard, however, opposes this view, because the temperature does not vary when the hyperemia declines ; because hyperaemia occurs when the fifth nerve is divided, but is attended with diminished temperature ; and because ligature of the veins of each ear, and consequent gorging of the vessels with blood, lowers the temperature of the parts, which again rises on the side on which the sympathetic is subsequently divided. It is true, that if the carotid be tied, and the sympathetic afterwards divided on the same side, no calorification takes place; but if the sympathetic be first divided, and calorification have come on, ligature of the carotid does not lower the temperature to that of the sound side. Another argument which may be used, in support of Bernard's opinion, is that the temperature in the para- lyzed parts exceeds, in some cases, by 2° or 3° the normal temper- ature of internal parts, as the rectum. On the whole, it seems to me decidedly most probable that the increase of heat is not solely due to hypergemic afflux, but that accelerated tissue change also plays a considerable part in its causation. It is a very important point, which is well illustrated by Brown-S^quard,' that the vital properties of the tissues in the range of the divided sympathetic are increased. He states that sensibility is augmented and persists longer; the sense of hearing seems to be more acute; the secretions of cerumen, tears, and perspiration are increased ; chloroform anaes- thesia occurs later in these parts than in others ; the first convulsions in strychnia poisoning take place there ; a galvanic current, too weak to act on the other side, produces contractions there; after death, the muscles and the iris remain contractile longer than usual ; the 1 Phys. of Central Nervous System, p. 141. 28 GENERAL PATHOLOGY. galvanic current of the muscles, detected with the galvanoscopic frog, is stronger than in those of the other side; cadaveric rigidity comes later and lasts longer, and putrefaction ensues later. Bernard doubts that the effect of dividing the sympathetic is to paralyze the arteries, and so cause their dilatation ; he seems to regard it as an anomaly that arterial paralysis should promote greater activity of the circulation. This, however, seems only natural, when we reflect that arterial contraction would necessarily have the opposite eifect, and would diminish the afflux of blood to the part. This is well seen when the arteries in the frog's web are made to contract by the application of cold ; whole tracts of capillaries appear empty, and deprived ef red corpuscles. On warming the web, the arteries immediately pour in blood abundantly. The old and oft-used phrase, "great arterial action," descriptive of a large and bounding pulse, when translated into correct physiological language means, of course, great cardiac action with a ivant of arterial. Some recent observa- tions by Bernard,^ show very clearly how paralysis of the sympa- thetic nerves increases and accelerates the arterial current. When a manometer was inserted into the right coronary artery of the lip of a horse, and another into the left, both instruments showed a pressure of 160 to 180 millim. The pressure of the blood increased 40 millim. on the left side after division of the corresponding cervical sympathetic. In the coronary veins of the lip, the instrument showed a pressure of 30 to 40 millim., which increased to 50 or 60 after section of the sympathetic, while the pressure again fell 20 millim. when the nerve was galvanized. As other results of division of the same nerve, were noticed pulsation of the veins, and a brighter colour of the venous blood. Analogous experiments made by other observers strongly corrobo- rate Bernard's statements. Jaschkowitz shows that section of the sympathetic plexus of the splenic artery causes congestion of blood, softening and distension of the capsule. If part only of the plexus is divided, the corresponding part only of the spleen is affected. Samuel, in experiments upon rabbits, dogs, and cats, found that the hypersemia of the intestinal mucous membrane produced by the extirpation of the coeliac plexus was so great that it exceeded all pathological hypersernias hitherto known. The secretion of the mucous membrane is increased by the operation, but not to the same degree as in violent diarrhoea. Wharton Jones finds that after removal of the lower part of the spinal cord and the roots of the nerves in a frog, the arteries of the webs retain all their contractility, or are even more than usually disposed to be constricted. If now the ischiatic nerve be divided on one side, "the result is, that the skin of the extremity subjected to the experiment becomes, even to the nal:ed eye, redder from vascular congestion than that of the opposite extremity ; and, on examination of the web under the microscope, ^ ' La Clia. Europ. 1859, No. 29, p. 282. Syd. Soc. Year-book, 1861, p. 29. GENERAL PATHOLOGY. 29 the arteries are found considerably dilated. In the web of the opposite extremity, on the contrary, the arteries are seen still much contracted, some even to closure.'' Instances have been observed in man where like results have ensued. A man cut his leg with a bay-knife ; profuse bleeding ensued, and nearly proved fatal. Ever after he observes that the wounded leg is hot and moist, while the other is apt to be cold. A patient of my own cut the inner side of the index finger deeply ; and after the wound had quite healed I found the distal part of that finger 2° hotter than the corresponding part of the middle. Algide fever, where the surface is icy cold, affords an example of the opposite state. The above statements show, in the clearest manner, how consider- able a control the sympathetic nerves accompanying the arteries have over the circulation, and the nutritive actions in a part. It is, therefore, certain that the influence of those vaso-motor nerves must rank very high in the pathology of all disorders attended with al- terations of the circulation. But, we have now to inquire whether these are the only nervous organs which act on the circulation, or whether there exist others also. The answer to this last question must be in the afiirmative. Ludwig's and Bernard's experiments show convincingly that stimulation of the third division of the fifth pair, and of the facial produces a greatly increased flow of saliva, while at the same time the circulation in the gland is accelerated. It is not known so certainly whether this is the case with other glands ; but with regard to muscles it seems sufficiently evident that their voluntary exercise coincides with increased blood-flow. The darker colour, increased bulk, firmness, and strength of a muscle that has been well exercised contrasted with the paleness, flaccidity, and wasted condition of one that has been long unused, can be ac- counted for in no other way than by admitting that the former has received a much larger supply of blood. If any further evidence were required, it would be found in the observations of Becquerel and Breschel, as to the increase of temperature which is produced by muscular exercise, amounting sometimes to 2° F. The pheno- menon of erection of the penis is, beyond doubt, dependent on a state of active innervation of the part causing increased afflux of blood. At certain times its occurrence can be perceived to be distinctly voluntary, and can be induced or prevented at the will of the indi- vidual. SamueP contends for the existence of fibres, distinct from the motor of muscles and vessels, as well as from the sensory, whose office is to preside over nutrition, and which are divisible into a centrifugal and centripetal set. The former, when excited, increase nutrition, when paralyzed decrease it. Paralysis of the centripetal fibres Samuel regards as the cause of the diminished resisting power of anaesthetic parts to injuries, &g. Fever and inflammation he ' Die tropMsche Nerveu, Leipzig, Wigaud, 1860. Canst. Jahresb., vol. ii. pp. 53-57, 1861. 30 GENERAL PATHOLOaY. explains as states of excitement of the trophic nerves. He records various experiments in which irritation of sensory and of compound nerves caused intense inflammation of the parts to which they were distributed. Thus irritation of the auriculo-temporal in the rabbit produces acute inflammation of the whole auricle, issuing in puriform eifusion, and inducing death by exhaustion. This inflammation did not begin until from three to six days after the operation, and most evidently was not traumatic. Irritation of the gangliform plexus of the vagus on one or both sides caused general and intense pneu- monia. From these statements, I think we cannot doubt that cer- tain nerves, when stimulated, do exert a very considerable influence in the districts to which they are distributed, in the way of increasing the amount of blood circulating through the tissues. Herein they exactly antagonize the ordinary vaso-motor nerves accompanying the arteries, whose activity induces the opposite condition. For the present it must remain doubtful whether these so-called trophic nerves are indeed a special set, or whether the same efi"ects may not be produced through ordinary motor and sensory nerves. The latter view seems the most probable, and is strongly corroborated by the atrophy of the hands and feet, which occurs as the result of the ansesthesia of Indian leprosy. (IX.) Some common facts, of daily occurrence, are worth consi- dering in reference to the above doctrines. It seems that there exists a kind of alternation between the action of the vaso-motor and cerebro-spinal nerves, the period of activity of the one corres- ponding to that of quietude in the other. Thus, while we remain at rest, the temperature of the surface of the body generally, and especially that of the limbs, is decidedly lower than when we are in active exercise, and the cutaneous bloodvessels are comparatively contracted and small. This condition, when it is somewhat excessive, produces the cold hands and feet from which not a few persons suffer. On the other hand, there are instances, though less frequent, where the reverse seems to be the case, and the hands and feet are prone to be hot and bedewed with excess of secretion. In the former it is clear that the cutaneous arteries are habitually contracted, in the latter relaxed. Now, it is certainly remarkable that voluntary exercise of the muscles should so speedily aff'ect the distribution of blood to the cutaneous surface. We might have expected that it would have caused an increased flow to the muscles, according to the function assigned to the trophic nerves ; but we should scarcely have surmised a priori that an active state of the musculo-motor would coincide with a paretic of the vaso-motor nerves of the integu- ment of the same limb. The fact, however, is unquestionable, and it is worth inquiring how it comes to pass. There seems no other ex- planation than that the vis nervosa of the centres, which while the muscles are at rest can act only on the vaso-motor nerves, is with- drawn from the latter to a great extent when these great organs are put into action, and, consequently, the cutaneous and other arteries GENERAL PATHOLOGY. 31 become dilated and permit free access to the blood. That this is really the case is tolerably clear, I think, from the circumstance that not only the vessels of the integument of the working muscles are relaxed, but those also of distant parts, as the head, which are not specially active. A rower, or a pedestrian wending his way up a mountain pass, finds the toil-drops fall thick and fast from his brow, though his brain is far less active than it was when he was engaged in his study. The influence of cold also goes far to prove that the relation of the phenomena to each other is such as I have suggested. It is certain that in cold weather we are capable of much more muscular exertion than in hot. On a cold day we can walk briskly with a weight of clothing which would be intolerable on a warm ; the cold evidently increases our muscular force. At the same time, we find that our limbs do not warm nearly so readily, though they may be well wrapped up, and sensible perspiration is with difficulty induced. This is because the greater amount of vis nervosa not being so soon expended on the voluntary muscles, keeps the arteries longer contracted. Again, it is well known that horses, who are in good training, will do their work with much less sweating than those who are out of condition. Patients suffering with neuro- lytic disorder often complain that the least exertion causes them to break out into perspiration, while, as they improve, this tendency diminishes. Here, again, we see a positive relation between nerve- power and vascular dilatation. The increased secretion from the cutaneous surface may be reasonably supposed in a state of health to be the result of an increased supply of blood to the perspiratory glands, and we have already seen that such has actually been found to result from the hypersemia induced by dividing the vaso-motor nerves. We may, therefore, I think, fairly surmise that what takes place on the cutaneous expansion and glands takes place also in in- ternal lining membranes and glands, and that thus by means of the free flow of blood to all parts the general nutrition is more per- fectly carried on. One chief cause of arterial dilatation, when the muscular coat is relaxed, is of course the pressure of the column of blood driven by the heart. Now, during exercise the action of the heart is increased ; and it is interesting to inquire how this occurs. Moleschott's ex- periments show that a weak stimulus applied to the vagi increases the frequency of the pulse ; yet it is also almost the universal testi- mony of all observers that division of these nerves greatly acceler- ates it. In one experiment of my own, the rate was nearly doubled. It seems, therefore, that paresis of the vagi may be looked upon as a probable cause of acceleration of the heart's action ; and this paresis would be produced in the same way as that of the arterial nerves. Moleschott asserts that the sympathetic has the same in- fluence on the heart as the vagus, so that all the cardiac nerves would be affected in the same way. Moreover, paresis of the coro- nary plexuses would have the effect of admitting a larger supply of 82 GENERAL PATHOLOGY. blood througli these arteries to the muscular tissue of the heart. This would certainly favour, if it did not set up, increased action of the organ. There exists evidence to show that heat has a stimu- lating effect on the movements of the heart ; and it is probable that the increased temperature of the blood in febrile states is concerned in causing the rapid pulse. But the acceleration of the heart's movements by muscular exertion ensues too rapidly to be ascrib- able in any great degree to this cause. In feeble persons, palpita- tion and quickening of the pulse on any slight muscular effort are familiar occurrences ; and it may be said generally, that the greater the debility, the more readily does the change in the cardiac rhythm occur. There can be little question that the two phenomena are really related to each other, and it is difficult to see any more prob- able connection between them than that which I have suggested. It is evidently in accordance with the plan of the circulation, that dila- tation of the arteries should concur with increased action of the heart. If the reverse was the case, we should have the heart's energy wasted in endeavouring to overcome the undue resistance of the vessels. As it is, however, the central impelling organ puts forth its activity at the time when it can be really effective. Some of the phenomena of disease accord remarkably with the above views. The rapidly-acting heart of the patient prostrated by low fever is often greatly quieted by wine. The quick, feeble, irregular pulse of cardiac dilatation is not unfrequently made steadier, slower, and stronger by digitalis, which is certainly a cardiac stimulant. The degree of acceleration of the pulse produced by sitting up in bed is a good indication of the extent to which a patient is exhausted by fever, or any other asthenic disease.' In the affection termed "goitre exophthalmique," the heart's action is often remarkably ex- cited, the carotid and thyroid arteries uncontracted, while the gene- ral condition is mostly one of great, perhaps extreme, debility. The application of cold to the cutaneous surface exerts, as is well known, a striking influence on its contractile tissue, producing the so-called goose-flesh. This is not (at least necessarily) the result of direct stimulus, as it is equally produced when the cold is applied to another part of the surface. Thus, a cold wet towel flapped oh the back immediately causes contraction of the cutaneous muscles on the anterior part of the trunk, which, of course, can only take place in a reflex manner, the stimulus of the cold to the sensory nerves being reflected on the vaso-motor, and those which influence the cutaneous fibres. This contraction, it may be remarked, is pre- cisely the same to all appearance as that which results from direct stimulation of the tissue by the interrupted current. It seems highly probable that the same contraction of organic muscular fibre takes place in internal parts when cold afFusion is applied to the surface, since there is no reason why we should suppose the stimu- ' Graves, Dublin Hospital Reports, 1830, v. p. 469. GENERAL PATHOLOGY. 33 lant impression to be reflected on the nerves of the skin alone. Indeed, there is actual proof that such is the case ; for we find that the heart's action is notably influenced by the cold shower-bath. Dr. Sieveking states that when the bath was taken after the pulse had been increased by exercise, the average depression in twenty observations amounted to 8.05 beats. When the bath was taken immediately after rising, the average depression in thirty observa- tions was 6.14, and this was not counteracted by subsequent exercise, which only increased the pulse on an average by 3.21 beats. These results were obtained upon a person in good health, and in whom sufficient reaction occurred ; but it is probable that in a less vigorous subject the depression would have been still greater. In fact, what happens when reaction is insufficient seems to be this — that the heart's action continues depressed, and the arteries generally con- tracted, so that free flow of the blood-current is prevented. The depressing action of the bath should be but temporary, and should be succeeded by the opposite condition. Dr. Brown-Sequard avails himself of this natural tendency of the vaso-motor nerves in his recommendation of the alternate application of cold and heat to procure the healing of bed-sores arising from defective circulation. Dr. Bence Jones's observations as to the effect of prolonged cold aff"usion show that it has a most powerful sedative eff'ect on the heart, reducing the pulse thirty to fifty beats in a minute, and often rendering it quite imperceptible. When the water was cooled down to 50° F., the eff'ect was much more rapid. In the treatment of acute mania, the cold douche has long been recognized as a most efficient sedative to an excited nervous system ; and, indeed, much judgment may be requisite so to employ it as not to induce serious, or even fatal depression. A patient of Dr. Currie's, who had derived benefit from cold affusion during the hot stage of an ague-fit, nearly died from the alarming depression which resulted from the same application while he was in the cold stage. The facts now referred to set in a clear light the great influence which the state of the nervous centres has on the results produced by the impressions conveyed to them. The latter may remain the same, but the effects will vary greatly according to the condition of the recipient centre. Thus, the shock of cold speedily causes in one person activity of the circulation and vigorous action of the heart ; while in another the primary depression persists, and is never suc- ceeded by the opposite state. It is a point well worth remarking, that when the arteries are contracted by cold, the capillaries and veins are often filled with stagnant venous blood. This condition may sometimes be well seen in the frog's web; and we may then observe how speedily the congestion is dissipated by warming the web and relaxing the arteries, so as to allow free blood-flow to take place. A good example of this kind of congestion was presented to me the other day in a man suff'ering from a small abdominal aneurism. An ice-bag had been applied over the tumour, and all the area of in- 3 34 GENERAL PATHOLOGY. tegument where it lay was of a dusky venous red, wliile the sur- rounding skin was quite pale. On laying my warm finger on the chilled skin, the venous hue quickly disappeared from that part. The foregoing remarks illustrate the converse occurrence to that first ex- amined; they show how depression of the heart's action, the result of a stimulus, coincides with constriction of the arteries. The ob- servations of Drs. Bence Jones and Dickinson^ are very interesting as to the effect of a very hot vapour-bath taken just before the cold douche. They found that the increased action of the pulse produced by the exposure of the body to hot steam prevented that depression which would otherwise have arisen from the cold water. The action of heat is certainly relaxing to the muscles of the skin and the arteries ; so that it is quite intelligible how in the above experiment it should have obviated the over-stimulating eftects of the cold — rendering both the coronary arteries of the heart, as well as those of the body generally, less prone to constriction. (X.) The relation which the febrile state bears to disorder of the nervous system is a topic of high interest. It did not escape the notice of Hippocrates, as shown by his aphorism, Uvpstoi %vst artaaixovi. The essential phenomena of fever seem to be increased temperature, more or less prostration, and derangement of the nervous functions; disorder of the secretions, and impairment of nutrition generally. The intention of the following remarks is not, of course, to notice any particular kind of fever, but to endeavour to trace the extent in which the phenomena of fever in general can be explained in refer- ence to neuro-pathology. Debility of the cerebro-spinal system does not seem, per se, capable of producing fever. We see patients con- tinually who are extremely weak, with a small and languid pulse, yet quite without fever. On the other hand, mere exhaustion from muscular exercise does seem sometimes to set up fever. I know myself two individuals in whom this has occurred. Again, all the phenomena of the earlier periods of fever are indicative of depression ; and in the prevailing fevers of our day, the stamp of debility is apparent throughout. There is much in the facts above stated as to the influence of the vaso-motor nerves to suggest that paralysis or weakening of their power may be an essential condition in fever. If we suppose the effects produced by dividing the sympathetic in the neck to be general, to occur all over the body — which is quite conceivable — there would ensue general pyrexia. In fact, we are sure that elevation of temperature and relaxation of arteries cannot exist with any other than a paretic condition of the sympathetic. Taking first for consideration the ordinary low or asthenic fevers, with which we are familiar, let us see how far "we can account for their phenomena on the assumption that the poisonous miasma has weakened the vaso-motor system, as well as all the others. The increased temperature — the quick, but soft and weak pulse — the Vid. Proc. of Med.-Chir. Soc, yoI. i. p. 77, 1857. GENERAL PATHOLOGY. 35 hyperoeraias of various viscera, may all, according to the foregoing views, be regarded as natural results. The increased secretion of urea may be accounted for partly by the augmented chemical changes which take place in the mass of the blood (considered for the time as a solid tissue) uncontrolled by the sympathetic nerves, and partly by the increased amount of renal action, depending on the same cause. ^ The hypertrophy which affects the glandulse soli- tarige and agminatge in typhoid may be also traced to the same ner- vous paresis, and may be regarded as analogous to the enlarged spleen of ague, or the goitre of Swiss malaria. To regard this hypertrophy as an attempt at elimination seems to me quite a mis- take. It is no more to be considered such than the enlargement of the correlated mesenteric glands is, which takes place at the same time. Both are similar structures, and both hypertrophy under the same conditions, viz., hyperasmia and loss of nerve influence. The condition of the other systems in low fever quite corroborates our assumption as to the condition of the sympathetic. The quiet mut- tering delirium, the unconsciousness or half consciousness, testify how the brain is enfeebled ; while the down-sunken posture in bed and the subsultus reveal the extreme muscular debility. The feeble- ness of the heart's action and the softening of its texture prove how its vital energy is depressed. The readiness of the skin to slough shows how its nutritive power is impaired. In certain cases, it seems as if the sympathetic system was but little affected, and the main stress of disease fell upon the cerebro- spinal. This one may conclude to have been the condition in the instances mentioned by Graves'^ {v. loc. cit.), where he says, " It was very curious to see a patient with a skin of a natural temperature, a perfectly natural pulse, tranquil respiration, clear eyes, no headache, a soft and fallen abdomen, incoherent, or with a low muttering delirium, excessive subsultus, extreme debility." Let us now turn to the opposite type of fever, the sthenic, marked by strong, frequent, full or hard pulse, dry hot skin, intense head- ache, active delirium, laboured respiration, diminished or suppressed secretions, in which bloodletting is not only tolerated, but may be essential to the preservation of life. It is evident that in such cases the greater part of the organs must be in a very different vital state to that which exists in low fever, where stimulants are for the most part of prime necessity. Let it be assumed that the poison acts primarily upon the sympathetic system, limiting its action to it, as woorara does to the motor nerves: increased heat will be developed, and subsequently a tendency to local congestion, varying in situation according to the part where the paralysis is greatest. The increased temperature of the blood will act as a stimulus to the heart, whose • Oppler has shown that the kidneys actually form a considerable proportion of the nrea secreted.

Med., p. 157. 86 GENERAL PATHOLOGY. tissue is vigorous (not debilitated, as in asthenic fever), and capable of responding energetically. The heart's action will thus be in- creased, and thus the character of the pulse is explained, except as relates to its hardness — a point we shall presently notice. The very interesting experiments of M. Calliburc^s, mentioned in Bernard's Lecons (vol. ii. pp. 395 — 403), corroborate the opinion advanced above, that the increased heat of the blood is the cause of increased cardiac action. He found that when the leg of a frog was dipped into warm water, the heart constantly contracted more frequently. Thus, the number of pulsations in three separate trials being 52, 32, 42 at the commencement, a temperature of 51°, 50°, 55° raised (respectively) the number of the beats to 90, 64, 100. Similar results were obtained when the heat was applied directly to the heart. Ligature of the vessels and section of the crural nerve did not prevent the increase of cardiac action from the application of heat to the leg. He concludes that the acceleration of the heart's action by heat is owing to the direct action of this agent upon the circulatory centre. That a high external temperature, which nota- bly raises that of the body, quickens the pulse, is certain. Blagden,^ on exposing himself for eight minutes to a temperature of about 260° F., found his pulse rise to 144 ; and Constantine James, ^ in hot moist air of about 100° F., found his pulse to reach 120, while his tem- poral arteries beat forcibly. The acceleration of the pulse may be owing in part to the enfeebling influence of the poison affecting the vagi nerves ; but the increased strength of the heart's contractions must depend on the dilatation of the coronary arteries and the free circulation of blood through its muscular tissues, whose vital power is thus temporarily increased. The hardness of the pulse in certain (sthenic) fevers and inflammations, implies a contracted state of the arterial coats. This, if general, is an opposite condition to that which is produced by section of the sympathetic, and, therefore, demands explanation in an hypothesis which is based on a presumed palsy of the system. It is to be remembered that arterial dilatation is by no means inseparably connected with increased blood-heat ; that the latter persists when the hypergemia, which the former occa- sions, has materially subsided. In sthenic fevers, it may fairly be presumed that the arterial coats, like the heart, retain for a time excitability, and contract, therefore, moderately under the direct stimulus of the rapid blood-current which traverses them. The pulse is, therefore, hard. In low fever, on the contrary, the pulse is soft, because the poison impairs at once the vital power of the arterial coats, as well as that of their vaso-motor nerves. Pyrexia, or the fever of inflammation, may next be considered. It is, probably, excited by a morbid impression conveyed from the inflamed part to the sympathetic centres ; in consequence of which, by a reflex inhibitory action, the vaso-motor nerves generally are ' Brewster's Nat. Magic, p. 311. * Gaz. Medic, April 27, 1844. GENERAL PATHOLOGY. 37 enfeebled, and so, as in other cases, fever results, with increased cardiac action. The production of pyrexia is the ordinary case ; the exceptional is that already mentioned [vide p. 22), where irrita- tion in some organ occasions paralysis of musculo-motor nerves. On the view just proposed, it is intelligible why the administration of tonic and nervine medicines is injurious in the pyrexia of sthenic inflammation, while it is beneficial in that of asthenic. The inflamed tissue being highly sensitive and impressionable, becomes further irritated by the tonic remedy ; and so the morbid impression con- veyed to the centres, and reflected on the vasomotor nerves, becomes intensified. By the employment of tissue sedatives, on the other hand, the morbid stimulus is annulled, and the fever movement subsides. This view assumes as certain a point which, though admitted by most of our best authorities, seems to be often ignored in the present day. I mean the existence of forms of dis- ease which, though aff"ecting the same part, and called by the same name, are as essentially dift'erent in their nature and tendencies as can possibly be — and this, too, independently of the original vital power of the patient. The distinction between sthenic and asthenic forms and phases of disease seems to me to be one of the leading truths in medicine ; and I cannot conceive how any one with the evidence of his daily experience before him, can think lightly of it. To take but one instance. It is unquestionably true that cases of erysipelas do occur, mostly among the rural population, where free venesection is positively beneficial, as well as purging and other lowering means. On the other hand, we frequently have to treat cases of the same disease where the only indication, and that an urgent one, is to stimulate very freely. The outside show of these cases is very similar, but how dift'erent are they in reality ! Sthenic disease is by no means synonymous with acute; the latter term has reference chiefly to the rate of progress, and may belong quite as well to asthenic as to the opposite class. One highly important character of sthenic disease is the state of the tissues with respect to their tolerance of any matters conveyed to them which are at all of an exciting quality. Let the skin be sthenically inflamed, as in eczema impetiginodes, and the arsenic or citrine ointment, which would benefit another case of a different temper, will grievously aggravate the disorder. On the other hand, when, in suitable cases of this kind, leeches, lead-lotion, salines, and antimonials have done their work, the same remedies which before were injurious prove healing. This is so because the vital condition of the tissue is now changed. Much of the " tactus eruditus" of the physician consists in being able to determine what cases belong more to the sthenic and what to the asthenic class, and in adjusting his remedies accordingly. The cause of the rigors of fever is a question of some interest. The phenomenon clearly belongs to the nervous system, and must 38 GENEKAL PATHOLOGY. be regarded as a kind of minor convulsion.^ It can be produced by various morbid impressions made on sensitive surfaces, as when a catheter is passed along a hyper^esthetic urethra, or, as in the case mentioned by Dr. Watson, where immersion of a recently-scalded arm in cold water brought on severe rigors. The forcing of a gall- stone along the narrow duct may have the same effect ; and so may a descending renal calculus. I have found, in my own person, very extensive irritation of the skin from harvest bugs produce even during very warm weather distinct though slight shivering. Simi- lar shivering was observed in the early part of catarrhal fever, evi- dently connected with cutaneous hyperiesthesia ; the sensation of coolness, which in health would have been very agreeable, being then actually repugnant. In malarious and other fevers the initial rigor is probably dependent on the action of the poison on the spinal cord, throwing it into a state of undue excitability, so that the nerves issuing from it keep the muscles in a state of clonic contraction, while the vaso-motor nerves maintain the organic muscles in a state of tonic. The same influence thus produces varying effects, accord- ing to the structures on which it acts. The rigors of pyaemia and of suppurating foci I should ascribe to the operation of contaminated blood on the nervous centres, and regard them, therefore, as having a similar causation to those of ague. On the other hand, those of hectic fever are most probably essentially dependent on nervous exhaustion, the centres falling into a state analogous to that existing in chorea, but manifesting itself in disordered actions of the vaso- motor more than of the musculo-motor system. Generally, there seem to be three factors concerned, or liable to be concerned, in the phenomenon: (1), a stimulus mostly of a morbid kind; (2), an altered hypersesthetic condition of a sensory surface; (3), a more or less excited or mobile condition of one or more nervous centres. In most cases the coexistence of two of these is necessary. Billroth^ states with regard to the rigors attending on fever of surgical affec- tions, that their principal condition is a very rapid increase of temperature ; another is a peculiar irritability of the patient, which may vary much in different cases, or in the same case at different times. He does not consider the rigors in pyaemia as necessarily dependent on blood-poisoning. There is no doubt that increased heat of the blood most frequently coincides with rigors ; but inas- much as they may occur where there is no fever {vide supra), and vice versa (as in an ague paroxysm having no cold stage), it seems to me most probable that the increased temperature is only a Co- pro- duct of the original cause. The poison by paralyzing the vaso-motor nerves causes fever, and by acting on the nervous centres produces rigors. Here we have an example of the generation of spasm and paralysis by the same cause. • Mr. Paget relates cases in which tetanic or epileptiform seizures took the place of rigors; v. Brit. Med. J., Aug. 16, 1862. 2 Via. Syd Soc. Year-book, 1863, p. 193. 0ENEKAL PATHOLOGY. 39 (XL) We may now pass to the consideration of some general points in reference to neuralgia ; a condition which in many respects contrasts strongly with fever, and rarely coexists with it. Schramm/ however, states that the remittent form of sciatic neuralgia in his experience has been generally attended with fever, and in many cases all the three stages of a paroxysm of fever (malarious) have occurred. The opposition of the two states is well manifested in some cases of malarious fever, where one febrile paroxysm in a series is, as it were, replaced by an attack of neuralgia. This, as well as the common production of some form of neuralgia by malaria, goes far to warrant the view that the morbid phenomena are deter- mined very much by the part on which the poison fixes ; pain ensu- ing if the cerebro-spinal nerves are specially attacked, fever if the vaso-motor, the exciting cause in both being the same. The preva- lent opinion respecting the nature of neuralgia seems to be that its existence implies an excited or over-active condition of the sensory nerves. Romberg uses neuralgia and hyperaesthesia as convertible terms, and states — in hypersesthesia we find that not only the irrita- tion is increased, but that also the irritability of the nerves of sensa- tion generally is exalted both during the paroxysms as well as the intervals. It is very evident that we can have no knowledge from actual observation of the state of the affected nerves during the attack. We must form our conclusions as best we may from con- sideration of the attendant circumstances, the "juvantia," and the relation of the disorder to others. For the moment let us put aside all cases of neuralgia which maybe regarded as depending on a local irritation of any kind — either direct, as a splinter imbedded in a nervous trunk ; or remote, as a worm in the bowels ; or, again, on demonstrable poison generated in the system, as in gout, or received into it, as in lead intoxication. There remain, then, all those cases in which the disorder is dependent upon no ascertain- able cause, except it be malaria, a draught of cold air, exposure to damp, overwork of mind or body, or some other cause of exhaus- tion. These form a group which may be distinguished as Non- organic or Immaterial Neuralgia. Now, in these the existing debility and prostration is at least very often almost as marked a symptom as the pain. It is also more abiding and unvarying ; and the conviction becomes wrought in the mind of the observer that it is the fundamental state upon which the pain is, as it were, en- grafted— the appropriate soil, without which the morbid germ would not grow. It is proved by experience that unless this debility and prostration can be to a great extent removed, and replaced by healthy vigour, no real progress ,can be made in the cure of neu- ralgia. The task is like that assigned to Sisyphus : the patient's and the physician's hope is worn out by ever-recurring relapses. The debility seems in a special manner to affect the nervous system. ' Bayer, Arztl. lotelL, Bl. 34, 1859. 40 GENERAL PATHOLOGY. The brain is languid and dull, and inapt for mental labour ; some- times its function actually fails, and delirium occurs. Stimuli are beneficial — often very markedly so, thougli their effect is temporary. Fresh pure air, good food, sufficient repose, alternating with exhila- rating employment, supplemented, if need be, by nerve-tonics, are the real remedies ; and just in proportion as they increase the general tone and strength, does the patient attain complete recovery and immunity from relapses. On the other hand, just as surely do all causes of debility confirm, increase, and render inveterate the malady. Now, it may be fairly argued that where the signs of debility, and specially of nerve debility, are so apparent, and have so distinct a relation to the particular symptom, this must be itself of like essential character. It can hardly be that the morbid state of the nerve affected can be greatly different from that which pre- vails so generally throughout the system, especially when we con- sider the means which avail for the cure of both. Rombero-'s metaphorical expression with regard to aneemic hypera3sthesia (neu- ralgia), that "it seems as if pain were the prayer of the nerve for healthy blood," is in all probability exactly true. The nutrition of the nerve being ill performed, its structure undergoes some mole- cular alteration which conditionates pain. What is true of neuralgia from this cause, I believe is true of all cases belonging to the im- material class. Electrical disturbances, damp cold, malaria, seem to me all to act in the like way, as far as we can judge — viz., by deranging the molecular nutritive actions of the nervous structure, and so unfitting it for fulfilling its function. There are several circumstances which seem to me strongly to support this view. One is the very frequent coexistence of numbness along with the pain, especially in highly sensitive parts, as the fingers and hands. One cannot say wherein the condition producing numbness differs from that which gives rise to pain ; but it is clear that there is no opposi- tion between them : both are often present together, and the numb- ness commonly remains as the more permanent condition in the intervals of the paroxysms of pain, and even after they have ceased to occur. Now, numbness is evidently a failure of functional power. Of the same import is the occurrence of various degrees of muscular paralysis, which is often associated with neuralgia, evi- dently as an analogous affection of the motor nerves. It yields generally to the same treatment. The phenomena of myalgia may also be referred to in illustration of the nature of neuralgia. Here the intimate relation of pain to debility is very marked : the sensory nerves of the muscles suffer because the associated motors are weak: whatever increases the debility increases the pain, and vice versd. In many well-marked neuralgic affections there is evident paralysis of the vaso-motor nerves in the seat of the pain ; the vessels are injected, and lachrymation or some similar phenomenon ensues. This makes it probable that the sensory nerves are in a similar state. Lastly, we may allude to the cure of neuralgia by Faradization as GENERAL PATHOLOGY. 41 an illustration of its nature. The pain of a sensory nerve and the paralysis of a motor may both be removed by the stimulus of the interrupted current. This surely indicates that both states are similar. Even in organic neuralgia, it seems to me open to much question whether the affected nerve is in a state of exalted excita- bility, or simply of deranged and disordered nutrition. In lead- poisoning, the motor-nerves of the muscles are certainly paralyzed, the pains are diminished "by pressure and friction" (Romberg), and the whole phenomena are indicative of diminished rather than of increased vital action. In gouty neuralgia, if we take colicky and spasmodic affections for examples, the disorder is much more of an asthenic than of a hyperaesthetic character. The pain and suffering attending a characteristic outbreak of gout in the foot have much more the features of hypersesthesia than the colicky disorder. The latter usually requires some stimulant for its relief, and can by no means be dealt with as the articular inflammation. , That a nerve which receives for nutrition blood poisoned by uric ) acid should be disordered in its acting, and thrown into a state , conditionating pain, is very intelligible ; but it can hardly be re- garded as having its functional power exalted. On the other hand, the nerve lying in a focus of inflammation by reason of the active hyperaemia would seem really to be in a state of hypersesthesia. Its condition is analogous to that of the nerves of one posterior limb in Brown-S^quard's experiment of transverse semi-division of . the dorsal cord, where hypersesthesia is produced in consequence of the hyperasmia resulting from paralysis of the vaso- motor nerves. Again, where neuralgia results from the impaction of a spiculum of bone, the development of a tumour or the like in a nervous trunk, although severe pain may be produced, it does not seem very clear that the nervous irritability is necessarily exalted — i. e., that the nerve-filaments, either on the distal or proximal side of the irritant, are more sensitive than they would be naturally. In a case of neuroma of a portion of the auditory nerve recorded by Mr. Toynbee,^ the only symptom was a diminution of the power of hear- ing. In a case reported in the Duhlhi Medical Journal,^ a female, set. 27, had a neuromatous tumour of the size of an almond developed in the course of the median nerve. If anything, even her dress, touched the tumour, severe pains shot down to the hollow of the palm, and upwards to the shoulder. She complained much of numb- ness and coldness of all the parts of the hand supplied by the median nerve. The nerve was cut across, and the neuroma re- moved. Fifteen months after the operation, she was quite free from pain, and observed nothing abnormal except a remarkable coldness of the fingers supplied by the median nerve. It is clear in this case that the neuroma, while it occasioned pain, did not increase the sensory power of the nerve. In some cases, however, it is » Patholog. Soc. Report, 1851. 2 Dublin Med. Journ., May, 1848. 42 GENERAL PATHOLOGY. certara that the peripheral nervous filaments are truly liypersesthetic, as in the case related by Romberg (vol. i. p. 37-44). In this, how- ever, the hypersesthesia may be accounted for by the increased supply of blood sent to that side of the face, the arteries pulsating strongly, and the eye being bloodshot and prominent. The same explanation applies to many other cases where the neuralgia is complicated with hypergestbesia, but not to all. In any case where the sensitive power of a surface appeared to be actually exalted, so as to be unusually keenly alive to the contact of external bodies, there would, I think, be reason to look particularly to the state of the nervous centres. Hysteria, hydrophobia, tetanus, and certain toxic conditions, afford good examples of central hypersesthesia. At the same time, I think it must be admitted that there is also such a condition as peripheral hypersesthesia, of which we have examples in photophobia, gastric irritability, and cutaneous pruritus. This is certainly a very different state from neuralgia, especially in relation to remedies, but has affinities with it. It occurs under nearly the same causative conditions. Hypersemia from vaso-motor < nerve paralysis is by no means a necessary antecedent. The above • view respecting the nature of neuralgia and hypereesthesia is strongly supported by the occasional occurrence of acute pain and tender- ness in limbs afi'ected with embolism of the main artery. Motor and sensory paralysis are constant, but in some instances there is also pain and hypersesthesia. Mr. Erichsen describes arteritis as attended with excessive sensitiveness of the surface, and with deep- seated burning and lancinating pain striking through the limb in different directions. The hypereesthesia persists even after the limb has begun to get cold and pulseless. From the preceding discussion we pass to the question — What is the seat of neuralgia — the nerves or the centres ? Obviously, this is no easy question to answer. According to the law of eccentric phenomena, every sensation of which we are conscious is referred to the peripheral termination of the sensitive fibres (so Romberg writes). Bowman and Todd add, that the sensation is referred to those parts, and to those only, to which the fibres irritated are dis- tributed. According to this view, all appreciation of sensations as referred to any point in the course of the nerve is out of the ques- tion. An irritation, wherever set up, must be felt at the peripheral extremity of the fibres implicated, and never in any part of their intermediate course. But there are facts which seem strongly op- posed to this exclusive dogma, and which go to prove that a sensation may be referred to various points in the course of the nerve-fibres. If we hit our funny-bone, although, no doubt, pain and tingling are felt at the peripheral distribution in the fingers, yet the chief agony is in the trunk of the ulnar nerve at the part struck, and certainly not merely in the skin covering it. The circumstance dwelt on by Valleix, that the specially painful points in nerves affected with neuralgia are always those where the nerve becomes superficial, is GENERAL PATHOLOGY. I 43 also a proof of a sensation being referred to other points besides the terminal. The same may be said of the pains •which patients describe as shooting down along the track of a nerve, as often ex- emplified in sciatica. These certainly are not located merely in the skin which covers in the nervous trunk. From these considera- tions I am led to admit the possibility of very numerous exceptions to the law of eccentric phenomena, and to believe that pain in a nerve may really indicate by its situation the seat of the irritation, or rather morbid action. This is a conclusion of some importance to the local treatment of neuralgia. It justifies our empirical habit of applying sedative remedies as near as possible to the seat (apparent) of pain. But, of course, we cannot affirm in any case of pain involving the trunk of a nerve that the morbid action may not be central ; the law of eccentric phenomena holds true, so far as that central disorder may certainly give rise to peripheral sensation. The only certain means of distinguishing the site of the pain causing action is division of the affected nerve. If this arrests the neuralgia, we know the disorder is seated peripherally ; if it fail to do so, we know that we . have to seek more centrally. In a very large number of cases, I fear, it must remain problematical where the real seat of the disorder is. If — the pain being specially referred to some intermediate spot — injection of opium subcutaneously at that part should give decidedly more relief than the same dose at a distance, it would afford ground for believing that the cause of the neuralgia was localized in that spot. In the ordinary way of rubbing sedative liniments on the i cutaneous surface covering the seat of pain, we have no means whatever of proving a local action on the suffering nerve, but rather the reverse. Foi", take the case of the sciatic, where pain is acutely ' felt at the back of the thigh, and notably between the ischiatic tuberosity and the great trochanter : if this be relieved by sedative applications to the covering tegument, we are sure that the chief action of the remedy must be on cutaneous ramifications of the gluteal, lesser sciatic, and branches of the external cutaneous and other nerves on the front of the leg. These will convey impressions to the spinal centre, not far from the part where the roots of the I sciatic are implanted ; so that if the neuralgia were of central origin, it is very conceivable that the morbid action might in this way be j beneficially modified. But, considering the depth at which the sci- I atic nerve lies from the surface, it seems quite impossible that the aconite, chloroform, opium, &c., should penetrate so far through 1 skin, fat and fascia, and even large muscles. There exists some '^evidence to show that any strong impression made on the nervous centres (such as cauterizing the ear, galvanizing the columna nasi — V. Duchenne's' work) through incident nerves may put a stop to ■ some neuralgias. This, if confirmed, would very much corroborate the view above expressed. ' Traits Therapeut., par Trousseau et Pidoux, vol. i. p. 787. 44 GENERAL PATHOLOGY. The pathological relations of neuralgia are, of course, very dif- ferent according to the cause which gives rise to it. If, however, we take the commonest kind — viz., that which arises from cold, malaria, or debility — we must allow that it manifests a very close affinity with non febrile rheumatism. Rheumatic and neuralgic pains are frequently so very similar, that they are only to be dis- tinguished by the action of remedies. Iodide of potassium cures the rheumatic, quinine and iron the neuralgic; while often it occurs that in the same case, after having begun with the former, we have to finish with the latter. The beneficial action of muriate of ammo- nia in neuralgia noticed by several recent observers can scarcely be dissociated from its remarkable and positive remedial action in mus- cular rheumatism. The interesting but obscure phenomenon of rheumatic paralysis is closely similar to, if not identical with, the paralysis or paresis of motor-nerves, which so often forms a part ■. of neuralgia. Catarrh is allied to neuralgia by the similarity of its I causes, the diffused pains in various parts, the resemblance of its ' inflammatory actions to those sometimes accompanying and depend- ing on neuralgia, and in a large number of cases by its "juvantia." I If exhaustion aggravates a neuralgia, so does it also a catarrhal ,! flux; while rest and toning means have an opposite effect. The af- i i finity between neuralgia and ague in malarious disorder is strikingly 1; apparent: the two disorders so evidently replace one another, that there can be little doubt that the difference is only one of situation; the sensory nerves being chiefly afiected in the former, the sym- pathetic in the latter. The therapeutical effects of arsenic, iron, and quinine in the two disorders rapprochent them not a little. (XII.) It seems a well-ascertained fact that the nervous tissue, ^ both in the centres and in the peripheral extensions, becomes more j excitable and mobile in proportion as its power becomes weaker. The motor nerve is more readily thrown into action, though the im- pulse it communicates is weak and cannot be long sustained. The ' sensory nerve is alive to the least impression, and becomes in certain cases gifted with almost preternatural acuteness. The brain is highly impressible, but incapable of any continuous effort; and ' headache is easily induced. Stimulants or tonics, which seem and are highly necessary, are tolerated with difficulty. The vaso-motor nerves rapidly alternate between a state of excitement, producing ' chills, and one of depression, giving rise to heat-flushes and per- spirations. It is very probable that this difference in the vital state / of the nerves depends on some molecular change in their composition, in consequence of defective nutrition; but no chemical research, that I am aware of, has yet proved such to be the case. Buhl's / examinations go to show that a state of unconsciousness coincides with a watery condition of brain, such as is apt to exist in anaemia. ' (XIII.) The tendency of nerve disorder to aggravation, or to make its first onset at night, is a very noteworthy point. Attacks of cholera and of choleraic diarrhoea, of epilepsy, asthma, and pare- GENERAL PATHOLOGY. 45 sis, are very prone to ensue at night; while^ neuralgic, rheumatic, and other kindred disorders, are almost universally aggravated at that time. A talented but woefully hypersesthetic female with whom I am acquainted, whose nervous disorder verges towards insanity, has for some time been always much worse towards the close of each day. In the malarioid remittent of children, the paroxysm is in- I variably nocturnal. The copious nocturnal sweats of phthisis and I of obscure aguish disorder seem to be referable to lowering of the ' power of the vaso-motor and other nerves during this period ; since we find tonic, astringent, and strengthening means to have a preventive effect. It is certain that malaria is most potent at night; and this is probably owing to the circumstance that the system is then less capable of resisting it. I believe a similar explanation applies to all the above cases. The morbid causes remain the same, but the nerve-power is feebler and less capable of withstanding them. It is not always easy to say how much of the increased morbid action may be owing to the state of sleep, or to the particular diurnal period. I believe that sleep does increase the liability to some affections, especially to sweating; but in most it is evident that this is not the principal cause, as sleep is entirely banished by the dis- order. , Another period at which nerve disorders of all kinds are very apt / to be aggravated is the catamenial. This is well called the monthly ' sickness, for it is certainly a season of lowered general and nervous /power; and it has repeatedly occurred to me to find improvement , which was previously going on smoothly interrupted by this some- I what troublesome interlude. (XIV.) It is impossible, in a work of this kind, not to take some notice of the theory which Dr. Radcliffe has espoused, and to the illustration and establishment of which he has devoted so much la- bour and skill. His general position, as conveyed in his own con- clusions {vide Lectures, Coll. of Phys., 1863, Lancet), is (1) that living muscle, when left to itself, is kept in a state of relaxation by the action of the natural electricity of the muscle; (2) that mus- cle passes out of the state of relaxation into that of contraction, when the attractive force which is inherent in the physical consti- tution of the muscular molecules is no longer antagonized by the action of the natural electricity of the muscle; (3) that the natural electricity which antagonizes contraction is extinguished for the moment by the instantaneous electrical currents of high tension i (analogous to the discharge of the torpedo) which are developed when muscle or motor nerve passes from the state of inaction into that of action, and that, ordinarily, muscular contraction is brought ( about in this way ; (4) that the natural electricity which antagonizes / contraction is extinguished permanently at a certain time after death, and that the permanent contraction of rigor mortis is brought about in this way. Further on, he states that he believes that the same conclusions are necessary with respect to the action of a motor 46 GENERAL PATHOLOGY. sentient nerve in sensation, as those which are necessary with re- spect to the action of a motor nerve in the production of muscular contraction. Radcliffe proposes to substitute these views for the doctrine that contractility is a special vital endowment of muscles and sensibility of sentient nerves, which on the application of stim- uli are aroused into functional activity. He applies his views to explain the pathology of convulsions, spasms, tremor, and pain — and concludes that all depend on vital exhaustion, and not on vital stimulation. It is impossible for me to attempt here any critical examination of the scientific experimental evidence which RadcliiFe so copiously adduces. I can only consider how far his main views are accordant with familiar and established facts, which cannot be left out of sight. The gist of his theory seems to be, that alike in health and in disease, muscular action as produced through the nervous system, and sensation, are the results, not of increased, but of diminished vital action. It appears to me, first, that he does not suiEciently distinguish between the nutritive process which main- tains the structure and vital properties of the tissues, and the func- tional action in which these properties (as we regard them) are brought into play. The former is, of course, directly. conservative, and can only tend to increase the vital powers of the part; the lat- ter is, from one point of view, wasteful, expending those properties which are generated by nutrition. It is, therefore, very conceiv- able that certain electrical currents and other phenomena should be interrupted during the period of a muscle's action, which go on steadily while it is at rest. Again, the common fact that muscles well exercised by their motor nerves gain in size and strength, while the reverse is the case when they are either unused or their motor nerves are paralyzed, seems very subversive of the theory. If mus- cular contraction implies diminished vital action of both muscle and nerve, how can it be that the frequent repetition of such weakening acts produces development and increase of vital force ? How can death cause life ? Again, it seems impossible to admit that a steady, sustained effort of voluntary contraction can be at all fairly classed with a clonic spasm of convulsive disorder, however violent. True, there are muscular contractions in both cases ; but in all other respects they differ widely. The kind of contraction is different : in one it is brief, violent, but unsustained; in the other, uniform, and steady. The state of the brain is very different: in one, active, conscious, with its functions of sensation and volition in full play, and its vessels traversed by full streams of arterial blood; in the other, the functions of sensation and volition in abeyance, and the vessels anaemic or filled with dark blood. The respiration and cir- culation in the convulsive attack are deranged from their healthy state. The fact that a very powerful emotion will sometimes animate even weak muscles to perform feats of extraordinary strength, seems capable of no other interpretation than that a higher amount of nerv- ous energy than usual is excited in the centres, and put forth through 0 GENERAL PATHOLOGY. 47 the nerves. The force so exerted is surely far greater than anj which could be developed in the rigor mortis, which is all that the muscle on Radcliffe's view can claim as its own. It seems, also, that Radcliffe makes no distinction between pain the result of some morbid action in a nerve or nervous centre, and a natural sensation : both he regards as the results of diminished vital action. This again seems quite erroneous. The morbid sensation is, as already shown, often associated with numbness, motor paralysis, and other signs of depressed vital power. But this is not the case with healthy sensation, which, indeed, requires for its perfection a state of active circulation in the sentient surface, as well as an active^ condition of the sensorium. Inflammatory pain is certainly of a different nature to neuralgia; it is intimately connected with active hypersemia of the affected part, and is unquestionably much more likely to be relieved by depletion and cold than by any stimulation. Certainly, no man would treat it in the same way as the pain of anasmia or brow ague. In the close of his lectures Radcliffe states that the pathology of pain agrees in all essential particulars with the pathology of tremor, convulsion, and spasm ; and that the pro- cess on which it depends implies vital exhaustion, and not vital stimulation. He advocates the treatment of all these disorders by supplying the weak nervous system with appropriate nutrients, such as oily articles of food and medicine, with phosphorus in various forms, by upholding and arousing the vital powers in general, and the nerve power in particular, by a stimulant plan of treatment, in which alcoholic drinks, ether, and phosphorus, in suitable doses, figure most conspicuously. The use of sedatives, as opium or bella-. donna, he discountenances. This quotation must, we think, con- vince any experienced man that Radcliffe's view is far too partial, and is by no means applicable to all the forms of sensation, healthy and morbid. The pain-relieving efficacy of opium, belladonna, and aconite, is as well established as any medical fact that we possess. That the morbid states he refers to are very often dependent on depressed vital action, there is no doubt; and we really are not aware that any one maintains the contrary. But to endeavour to prove that all phenomena involving motion and sensation, physiolog- ical and pathological, are of the same kind, seems to us contra- dictory to familiar facts, and we cannot consent to take any such principle for the basis of our practice. If prolonged experience convinces us more and more of any one thing, it is of the utter diversity and radical dissimilarity of many pathological states and symptoms called by the same name and outwardly seeming much alike. It is the fashion of the day to try to refer all disease to diminished vital action, and to assume (I think very unfairly) that previous authorities have always referred it to increased. It would be more correct to say that disease has been ascribed to deranged or perverted vital action which may be increased or diminished. Beyond this I believe w^e have not advanced yet. 48 CEREBRAL ANEMIA. CHAPTE R III. CEREBRAL ANiEMIA. As one of the simplest morbid states of the brain, we may take angemia, which properly implies a simple decrease in the amount of arterial blood passing through the organ in a given time. The observations of Kussmaul and Tenner on six male adults, backed by those which they made on rabbits, show very conclusively what are the results of this state when it is speedily induced. When both carotids were compressed in the human subject, the vertebrals of course remaining open, the principal phenomena were, pallor of the face ; loss of consciousness ; dilatation of the pupils ; slow, deep, and as.it were sighing respiration; and, in two cases of weak intellect, a choking sensation, followed by vomiting and general convulsions, which disappeared in a few seconds after the compression was re- moved. Ligature of the common carotids, one or both in succession, may produce no symptoms, or may cause paralysis and convulsions ; the convulsions aflfecting the same, and the paralysis the opposite side. The paralysis may precede, accompany, or follow the con- vulsions. The eye of the operated side sometimes becomes blind- Other symptoms which have been observed are, " dizziness, stupe- faction, insensibility, loss of consciousness, of speech, and of free play of the muscles in general ; difficulty in swallowing, nausea, vomiting, swooning, and coma." The authors whom we are quoting proceed to state that post-mortem examination traces the cause of the paralysis to anaemia and softening of the corresponding cerebral hemisphere, to a greater or less extent. They are satisfied that " epileptic convulsions only manifest themselves in man, when, together with the cerebrum, some or all of the parts of the encephalic mass lying behind the thalami optici are suddenly deprived of blood to a sufficient amount, but that sudden falling down, announcing the approach of an apoplectic attack (?), unconsciousness, and insensi- bility, originate in causes proceeding from the brain proper." The affection termed by Trousseau, " congestion cerebrale apoplecti- forme," in which he believes there is no congestion at all, but that the disorder is rather allied to epilepsy or syncope, seems to be essentially of anaemic character. A man falls down suddenly, as if stricken by apoplexy ; is taken up in a state of stupor, and for a quarter of an hour, or even longer, remains more or less in the same condition — his intelligence confused, and his gait uncertain. The following day he is quite well. In slighter cases, the patient is CEREBRAL ANEMIA. 49 attacked, all at once, with giddiness ; loses sight and speech, and staggers, sometimes falling down, but getting up again immediately. In three or four minutes he is quite recovered. In these cases, as in ordinary epilepsy, the face is pale at the commencement of the attack, and only becomes flushed afterwards. It is a curious circum- stance, which was observed in the compression of the carotid experi- ments above quoted, that on the removal of the pressure, the face became suffused. Indeed, Kussmaul and Tenner state, as a general result of their observations, that releasing the ligature from the cervical'arteries always produces temporary hypersemia of the brain. Profuse hemorrhage after delivery, says Dr. Gooch, will cause the woman to have a distressing headache, with throbbing in the head, ^ noises in the ears, a colourless complexion, and a quick, weak, often thrilling pulse ; all which symptoms are greatly increased by any exertion. Abercrombie^ describes how children may lie, for a day ' or two, in a state of stupor closely resembling coma from organic disease — insensible, with dilated pupils, eyes open and insensible, the face pale and the pulse feeble, and yet recover under the use of wine and nourishment. This state is induced by causes of gradual exhaustion, going on for a considerable time. It may occur in adults, though less frequently than in children. " It differs from mere exhaustion in the complete abolition of sense and motion, while the pulse can be felt distinctly, and is in some cases of tolerable strength." A case is related where deafness was induced by the erect posture, and hearing immediately returned in the recumbent. The patient was in a state of extreme weakness and emaciation. A weakly female, aged 22, under my care, convalescent from catarrh, stated that her head ached, and she became giddy and fell, when she threw her head upwards and backwards. Comparing syncope with apoplexy, Abercrombie says,^ " It is preceded by giddiness, tinnitus aurium, and impaired vision ; and is accompanied by blind- ness, dilated pupil, perfect insensibility, and not unfrequently passes into convulsion." (The Italics are my own.) Kussmaul and Ten- ner state that convulsions from hemorrhage do not ensue — (I) when the hemorrhage is slow ; (2) when the animals are very much de- bilitated ; (3) when the nutrition of the spinal cord has suffered; (4) when large pieces of the excitable districts of the brain have been removed ; (5) in animals subjected to etherization ; (6) doubtless, when the excitable districts of the brain have undergone certain • pathological alterations. The first and second clauses afford a rea- sonable explanation of the non-occurrence of convulsions in many cases of cerebral anaemia. Gooch's own personal experience, as he describes it, illustrates well the chief effects of cerebral anaemia in a chronic form. He says, any one who, from long defect in the organs of nutrition, is reduced so that he has neither flesh on his body nor blood in his veins, well knows what it is to lay down his f On the Brain, p. 309. 2 Ibid., p. 300. 50 CEREBRAL ANEMIA. head and doze away half the day without any congestion or inflam- mation of the brain. It is clear that in most cases, in all except those where cerebral anaemia is suddenly induced during a state of health, the condition will not be one of pure diminution of blood- supply, but of diminished and altered blood-supply. The system will be not only ansemic, but spansemic. Further, this state cannot exist for any length of time without modifying injuriously the nutri- tion of the brain, and rendering it more excitable and weak, accor- ding to the general law which we see so constantly exemplified. This altered vital quality of the great nervous centres may exercise a considerable influence on the subsequent phenomena, as has already been shown by the above- quoted statements of Kussmaul and Tenner. It is a most important fact observed by these excel- f lent inquirers, that arrest of the blood-supply to a muscle, and the / nervous apparatus with which it is connected, produces at first spasmodic contraction, followed after a time by complete paralysis. This is true in the case of the iris and the sphincter ani, and, no doubt, holds good with regard to the other muscles of the body. " Suddenly withheld nutrition" causes a sudden commotion, and molecular change in the dynamic matter, which acts in the same way as a stimulus on the nerves. The effect of slowly-impaired nu- trition, as just observed, is somewhat similar : it renders the nervous apparatus much more mobile than natural. On the other hand, good and full nutrition renders the nervous tissue much more calm and steady in its actings. We may now proceed to gather up into some general conclusions the chief results of the preceding discursive review. (1) It appears that anaemia of the previously healthy brain, when speedily induced, abolishes its functions and those of the chief organs of special sense. (2) When slowly induced, and associated with spansemia, it pro- duces eff"ects similar in kind, but less in degree, except in some ex- treme cases. (3) Ansemia of the cerebral hemispheres, even occur- ring suddenly, will probably produce unconsciousness, but not convulsions. This may be regarded as the pathological condition giving rise to the minor forms of epilepsy, the " congestion apoplec- tiforme cerebrale," and certain forms of vertigo. (4) The true complete epileptic paroxysm probably requires for its production an at least tolerably active and excitable state of the brain-tissue, and a suddenly induced anaemia, involving not only the hemispheres, but the medulla oblongata, or at least the pons Varolii and tubercula quadrigemina. (5) Venous hypersemia is well known to be equiv- alent in its influence on nutrition to anaemia. It may give rise to convulsion when it is rapidly induced in the brain, or to mere sopor when it occurs gradually. Of the first we have an example in some severe attacks of hooping-cough, and in apnoea. Of the second, the following instance came under my own observation. A male, set. 60, was under Dr. Sibson's care in St. Mary's with an aneurism of the aorta, pressing upwards towards the right, and bearing upon CEREBRAL ANEMIA. 51 the left brachio- cephalic and superior cava veins. His face, as well as the neck and upper part of the chest, was swollen, and of a deep dusky tint from venous congestion. The appearance was very much as if his skin had been darkened by nitrate of silver. The breathing was quiet, 17 ; pulse 96, open, soft, and equal in both wrists. The cerebral functions were much impaired. The patient remained constantly in a soporous state, very similar to that of the patients described by Abercrombie. There were no convulsions. The following cases, though not simple instances of cerebral anemia, are, I think, very illustrative of that state, and altogether are of considerable interest .* — No. 1. — H. B , 38t. 31j female, seen in consultation with Dr. Palmer, Jan. 14th. — For about seventeen years has led a very dissolute life, drinking at interval.'? large quantities of brandy and port wine. After these bouts she would remain sober for a time. Had jaundice and swelled ankles in Scot- land two or three years ago. No indications of syphilis. Her general con- dition five or six weeks before I saw her Dr. Palmer describes as sufficiently startling There was general oedema from the forehead to the toes, a pasty wax-like complexion, complete anorexia and almost hourly tenesmus, with pain in micturition. The motions consisted almost solely of jelly-like mucus. There was marked tenderness on pressure all over the liver, but nowhere else in the abdomen. Frequent vomiting. Urine cloudy, and usually de- positing red or pale lithates : it was examined again and again, but no albu- men was detected. Complains of severe pains across the under parts of the roots of the toes, like those of atonic gout : has pains also in the legs and insteps. Mental faculties blunted and dull. Pulse about 100. Amenor- rhoea for three months. Under treatment she improved ; the cedema almost disappeared, the skin generally began to look natural, but still she was very weak in mind and body. She could eat a little meat, and slept fairly. After having gone out and taken supper one evening, the symptoms recurred, attended with smart bronchitis of right lung. This subsided under treat- ment; but she remained in a feeble, semi-somnolent state, with frequent sickness and anorexia — Feb. 5th. Some appearance of peritonitis, no somno- lence, purged freely. — 9th. Several epileptic fits occurred yesterday and to- day ; is incoherent, scarcely knowing her mother, and using bad language. — 14th. Up to this date, incoherent, somnolent, talking, or screaming, with occasional periods of partial consciousness ; sometimes clutches eagerly at food, and eats a little ravenously. Sphincters do not act. Died same evening. My impression, when I first saw this case, was very decided that it was one of renal degeneration, with urasmic poisoning. The urine, how- ever, was unlike any that is usually passed in such states. I examined it carefully on Jan. 14 th and Feb. 5th : on neither occasion could I discover in it anything manifestly morbid, except that the last specimen deposited numerous nuclear corpuscles, which appeared to be those of renal epithelium. It was full-coloured, sp. gr. 1017 to 1012, thick, with amorphous lithates, and contained no casts or albumen. As to the amount passed, it was below the normal, but was not very scanty. At the post-mortem, we found evidences of slight recent peritonitis. The spleen was large, very dark, and contained several small fibrinous masses. The liver was enlarged, and in an extreme state of fatty degeneration, but free from cirrhosis. The kidneys were very flabby and lax, but not apparently wasted j their surface 52 CEREBRAL ANEMIA. was quite smooth. The matrix appeared thickened, the Malpig tufts nor- mal ; the epithelium seemed to have accumulated in the tubes in excessive quantity, but its particles were stunted and ill-formed. On the whole, it could not be said that the kidneys were at all incapable of functioning. The supra-renal capsules were carefully searched for, on both sides, but no trace of them could be found. There was much fat both within and upon the abdomen ; no bronzing of the skin : head not examined. This case goes quite to corroborate Traub's view,^ who ascribes uraemia phenomena to cerebral oedema and anaemia. Although the kidneys and their secretion were by no means perfectly normal, yet they were, I think, sufficiently so to make it pretty certain that the somnolence, delirium, and convulsions were not the result of poisoned blood. The nutrition of the cerebral centres was evidently seriously impaired for some weeks before death. The cause of the anaemia is obscare^ I am scarcely inclined to attribute it to atrophy of the supra-renal capsules, since these organs may be removed from animals without any bad effects ensuing. Moreover, simple atrophy might affect the system very differently to the usual atheromatous degeneration. It seems most probable that the anaemia, the supra-renal atrophy, and the degeneration of the liver, were coincident results of some general cause — perhaps of the intemperate habits. No. 2. — A. B., set. 46; March 28th. — A rather strongly-made man, of medium height, not at all anaemic, rather the reverse; hair gray. Has usually led an active life, much in the open air. Ill for fifteen months, had at first an attack of painful griping diarrhoea, with some rheumatism ; this was followed by loss or impairment of speech, so that he could not express what he wanted. In a few hours, with the aid of a glass of gin, he reco- vered. Subsequently, during the same journey in Australia, he was unable to get off his horse from stiffness and weakness in the left limbs. A week afterwards, his mouth was drawn aside a little. Two or three months later, having been quite v/ell in the interval, he had a severe attack ; for three weeks he was quite delirious, and was under medical care three months. He lost all his memory; was heavy and dull; but after a seton had been put in his neck, he became quite lively. He wears the seton still. He could not walk from giddiness at one time, nor use his right arm. Now he can walk, and has tolerably good use of the arm. He used also to have pain, and a sense of heaviness in the head, as well as a feeling of pins and needles in the legs; but these symptoms are much diminished. Pupils are now equal and natural. Speech slow, intellect does not seem vigorous, memory in particular is impaired. Right hand is unsteady; he cannot use it to write. No disease of the thoracic or abdominal viscera. Urine highly acid; deposits lithates. — April 10th. Seton removed; skin cool; head fairly cool; pulse weak and quick. — April 16th. Head seems too warm ; its circu- lation tends to be over-active. He says, however, that he has less pain in the head than he had a week ago, and that he can now stoop and move his head better without feeling giddy — 21st. Can write since his fore-arm has been faradized; not, however, as freely as he used; but this seems to be from a defect in his mental actions, rather than from any want of manipulative power. He finds he misspells words, and uses wrong ones, or cannot recol- lect the right. In speech he seems to have the same defect ; is slow in ' Schmidt's Jahrb., vol. cxiv. p. 308. CEREBRAL ANEMIA. 53 expressing himself, and does not recollect or comprehend as readily or quickly as he might. But he walks about well, goes long distances, and manages all his matters. Is remarkably active in mornings. — 30th. Was at the Crystal Palace the day before yesterday ; was fairly well last night, but had pain in head all night ; and this morning when he got up, he felt ill and weak. His mental power was much impaired, he could not find his way, dropped his gloves and handkerchief, lighted a paint-brush instead of a match, &c. I found him with cold skin and feet, head cool, lips pale, bowels open, no appetite, pain still in head, but no tenderness ; pupils natural. A dose of ammonia et spt. aeth. s. co. did not rally him. He had a hot mustard bath to feet and hands, was put to bed, and took hot brandy-and- water; after which he was better. He slept all the day, ate a tolerable dinner, and by the evening was free from pain in the head, and had regained his consciousness. — May od. Last night as he was going to bed, he suddenly became unable to see to read, and felt giddy. This passed oflF by the next day. His right hand has got more steady since the faradization, he can shave himself. — June 10th. He has had two or three small attacks since last report, always directly traceable to over-exertion and subsiding with rest and a little stimulus. In these his hands are cold, his pulse weak, he stag- gers, and his brain evidently fails to function properly. — 9th. Yesterday, he went to the Zoological Gardens, having been to the Crystal Palace the day before ; he remained well until dinner-time, when he seemed stupefied, and was unable to feed himself properly. When brought home, he was cold, with a feeble pulse, and could only mutter inarticulately. In the morning he was much the same, quite speechless. After hot coffee and brandy-and- water, his pulse rallied, and became full but soft, and his head hotter than before. About two hours after, finding him still unable to speak, and with an active circulation, I bled him to 14 ounces ; he bore it very well, but did not improve materially. He got out of bed himself some hours later, and walked down two flights of stairs. — 13th. Yesterday he continued in nearly the same state j but to-day at 11 A. M., he had a severe epileptic paroxysm, and another at 4 P. M. After the first, he had liq. opii sed. n\^xv, but did not sleep. The convulsions affected both sides, the right es- pecially; they lasted fifteen to twenty minutes. During their continuance, the face and neck were congested, and covered with sweat ; the eyelids were constantly opened and shut ; the respiration at one time was embarrassed. The second paroxysm ceased when I raised his head to put a seton in the neck. — 16th. Since the last report, he has had very numerous epileptic paroxysms, many of them very severe, and the intervals sometimes shorter than the attacks. He is quite unconscious; urine is passed in bed; body bathed in sweat. In evening of the 14th, he began to take morphia by Dr. Sieveking's advice, who saw him with me, and I administered chloroform by inhalation. By noon of 16th he had taken about six grains; the pupils were contracted, the pulse good, 96, and the epileptic attacks had ceased for twelve hours. — 18th. Remains still unconscious; no convulsions; he continued to sink all day, and died at 6 A. M. of 19th. During the last twenty-four hours, the right arm was evidently paralyzed. — P. M., twenty- eight hours after death. Scalp pale, cerebrum very pale. Arachnoid of surface white-spotted, lifted up by clear fluid which was abundant everywhere. The gray matter was everywhere very pale. The vessels appeared fairly healthy; there was no trace of emboli. All the parts, cerebellum, meso- cephale, medulla oblongata, and cerebrum, were carefully examined; but to 54 CEREBRAL ANEMIA. the naked eye there was no evidence of morbid change in any of them; only the roof of the ventricles was, perhaps, abnormally firm. Careful microscopic examination was made of the thalami optici, and corpora striata, as well as of the cerebrum, cerebellum, and medulla oblongata; but the only change that was detected was the deposition of orange-coloured pigment masses, along the vessels of the two cerebral ganglia, there was nothing else that could be pronounced certainly abnormal. In the fornix, however, the fibres seemed to be in great measure disintegrated. No exudation corpuscles were found anywhere. The heart was very flabby indeed, but the muscular tissue of the left ventricle was fairly healthy. Kidneys very flabby, but not diseased. Remarks. — The primary disorder in this instance is, unfortunately, obscure. All that can be affirmed is that it left no unequivocal traces of organic change, and yet it impaired and weakened the functional power of the brain It may have been an attack of congestion, or, what I rather incline to, an af- fection of the nature of sunstroke. There seems no doubt that the seton for some time was highly beneficial, but its removal was not apparently injurious. Some strychnia, which was given on two occasions, did not seem to have much effect, although it caused once spasmodic twitchings. The patient was of a very active disposition, and greatly disregarded my repeated admonitions to keep himself more quiet. The enfeebled state of his nervous power was clearly shown by the frequent recurrence of failure of cerebral function, generally in connection with over-exertion. The circulation was always depressed at these times; but this seemed to be secondary, and there was no indication of ordinary syncope. It appeared as if muscular exertion con- sumed the nervous force, and left the cerebral centres enfeebled. The last attack clearly was produced in this way. In this it was evident that it was not only depression of the circulation which caused the failure of cerebral power, but that the paresis of the latter, to some extent at least, was primary. This may be fairly inferred from the circulation having become vigorous without the restoration of the cerebral functions. The venesection had no immediate effect, either for good or bad; but there is too much reason for suspecting that it may have been concerned in inducing the convulsions which came on three days later, and caused death by asthenia. The results of the dissection, taken together with the history of the symptoms, incline me much to believe that the impairment of function proceeded rather from dynamic than from an organic defect, and that under more favourable cir- cumstances, nearly complete recovery might have been attained. Admitting — which is, I think, probable — that some amount of organic lesion had occurred, it seems from the history of the disorder that this was rather general than local, and probably it affected chiefly the gray matter of the convolutions. The anaemic condition of the brain after death certainly cor- responds very well with the symptoms which occurred during the last few days of life; and the supposition seems very probable that during the previous less severe attacks the condition of the brain was similar, especially as during these attacks the general circulation was evidently much depressed. How this failure of circulation was brought about is not at first sight clear; most pro- bably it is to be ascribed to the close commissural connection existing between the cardiac centres in the cord and the superior encephalic. We know that a sudden shock to the brain will powerfully depress the heart's action; and we may conceive that the central collapse would have the same effect in this case. On the other hand the slackening of the circulation would, of course, considerably increase the primary cerebral paresis. The sub-arachnoid effu- CEREBRAL ANEMIA. 65 sion was, I believe, the result of the paresis of the brain, whose nutrition was no longer adequately carried on, and so there ensued a kind of passive exudation from the bloodvessels to fill the space of the shrinking organ. The fatal convulsions resulted, no doubt, from the increasing debility, and anaemia of the eiJtephalon having produced, according to the general law, V. p., a state of hyper^esthesia of the excitable districts, the mesocephale, &c., which displayed itself in this manner. They were too prolonged, and recurred too frequently to have depended on mere spasm of the carotids and vertebrals, though this may have occurred at intervals, and had some share in the phenomena. Kussmaul and Tenner state that the brains of rabbits could not be deprived of blood more than two minutes without death actually ensuing. On the whole, I regard the case as one in which, owing to some unknown influence, such as sunstroke, the functional power of the brain had become much impaired, and was left in a condition liable to be still further de.pressed by slight causes. The morbid changes induced by cerebral angemia, in so far as they are demonstrable, are such as might have been anticipated. The insuflBciently nourished tissue falls into a state of decay, termed "white softening." This occurs in the human subject in about five days, or rather sooner, according to the reports which are given of the operation of ligaturing the carotid. It is no uncommon thing to find in connection with an angemic state of the brain after death an excessive amount of interstitial and sub-arachnoid fluid. This is secreted to take the place of the more or less shrunken cerebral mass, and is poured out all the more readily in consequence of the loss of tone in the coats of the vessels. According to Buhl's re- searches, this condition of a "wet brain" coincides with a tendency to stupor. In cases of softening, affecting part only of one hemi- sphere, resulting from embolism of an artery, it is affirmed by Panum' that the appearance of the softened part depends on the time at which it is examined after the deprivation of blood. Red softening com- mences in twenty-four or forty-eight hours, and lasts from eight to fourteen days : it is succeeded by yellow softening, and this again, after several months have elapsed, by white. The cerebral tissue in the affected part becomes gradually softened and more disinte- grated, and paler in colour, as time elapses. In red softening there is always increased tension and injection of the collateral vessels. The colour is produced not only by vascular injection, but by capil- lary extravasations. Subsequent changes consist in fatty degene- ration of the tissues and decolorization of the blood-globules. The diagnosis of cerebral anaemia is evidently a point of the highest importance, and one which may by no means be always easy. When the face is pale, the scalp cool, the eyes uninjected, the general circulation quiet — when there is no appearance of cerebral excite- ment, but rather of failing power — when the recumbent position affords relief, and the distressing sensations in the head are described * V. Meissner's Report in Schmidt's Jahrb., vol. cxvii., p. 209. 56 CEREBRAL ANEMIA. as a weight at the vertex, or a feeling of opening and shutting, and as if the top of the head Avere being lifted off — the nature of the case is clear. But there may be conditions of the most marked general angemia or spangemia, in which, of course, the cerebral circulation participates, and yet in which there may arise temporarily a state of cerebral hypersemia. By this I mean that though the blood is evidently of very imperfect quality, deficient in solids and in red cells, yet that an excess of this blood is sent to the brain above what it ought under the circumstances to receive. Nothing is more com- mon than to find anaemic patients complaining of headache from the administration of necessary tonics, because their nervous centres have been brought into such a state of hypersesthesia by the impaired nutrition that they can hardly tolerate anything of a stimulant nature. A little excess, therefore, even of spansemic blood, may cause distress to a- feeble brain, which after it has regained more healthy tone, will bear and be benefited by a larger amount of much better blood. The case is similar to that of the starved man, whose very preserva- tion depends on his being fed most sparingly for some time. The fol- lowing case is of interest both as regards diagnosis and treatment : — No. 3. — J. W., set. 31, smith, admitted August 4, 1862 — Is in a state of the most extreme anaemia from rectal hemorrhage, which commenced nine years ago, and has recurred at intervals ever since.

His head throbs; he has pain at the precordia, palpitation and giddiness in walking. Bowels usually loose. A hruit de diahle is heard on both sides of the neck, very loud whea he turns his head to the opposite side, feebly when he holds it straight. Skin cool; pulse feeble. No piles could be discovered.

His condition was rather one of soporose delirium than of coma. Opium was ordered, tt\^x1 of tr. opii stafhn, and it^xx o. h., until he appeared to sleep; but he would not take it, kept bis mouth firmly closed, and at 12 midnight I found him very rest- less, thrusting his head repeatedly into the pillow, and quite unconscious.

Remarks. — This man has been long under treatment, which had quite failed, because the source of the hemorrhage had never declared itself, as it happened to do while he w^is under my observation. There was not the least trace of piles when I first examined him, and I had no idea that any would be found. The case is instructive in this point of view, as showing how long concealed the cause of such serious hemorrhage may remain, and how closely it behooves us to search after the '' causa mali." But this by the way. The bearing of the case on our present subject is to illustrate how in the extremest anaemia a state of relative hyperasmia may arise, and bring the patient into serious peril. The brain in this man during his acute dis- order was evidently seriously implicated, irritated, and over-excited. His foi'cible struggling and resistance showed that it was no state of mere pas- sive stupor from failure of nutrition. The open, forcible pulse, the increased cardiac action, and the dilated pupil, as well as the heat of the surface, were evidence to my mind that the cerebral arteries were dilated, and that the weak and irritable brain was oppressed by an overflow of blood. There was grave reason to fear that ventricular or subarachnoid efi'usion was imminent, and that as this took place and the active congestion declined, fatal coma would ensue. Opium was given, with the view of contracting the arteries, and so by lessening the blood-flow of reducing the cerebral excitement. Though not administered so regularly as I wished, it was yet given in sufficient quantity to produce an eff"ect; and this certainly seems to have been benefi- cial. The blister did not rise very fully, and had not, in my judgment, much to do with the improvement. It was very remarkable how, as he be- came convalescent, the pulse grew small and weak compared with what it had been during the cerebral attack. This indicates the recovery of the sympathetic system from the state of paresis into which it had been plunged — V. p. It is a question of material importance to determine how far the state of the skin of the head and face may be taken as an index to that of the intra-cranial organs. One would think it a priori probable that the external and internal carotid and their branches would be influenced simi- larly by the nerves which supply their coats, and, therefore, that the state of the circulation would be alike in both sets of vessels. To a great extent I believe this is actually the case, though not invariably. It must be re- membered that the brain is very much more vascular than the skin, and also that it is supplied by two other arteries besides the internal carotid, which receive vaso-motor nerves from a diff'erent source. It is, therefore, quite conceivable that the brain might be receiving an excessive supply of blood, although the vessels of the external tegument were but moderately filled. Moreover, if there existed any tissue excitement of the brain, this would create an attraction of blood to the internal viscus, which would tend to 58 CEREBRAL ANEMIA. leave the external tegumeat in a minus state. However, I can speak from personal experience to the coincidence of a cold state of the skin of the fore- head, with overpowering drowsiness, i. e., cerebral anaemia, and to the con- verse. I have met with patients who looked at first sight most blooming, but who complained that their cheeks were burning and their heads throb- bing, and who wished, in fact, to be cured of their extra and intra-cranial hypersemia. As a general rule, if the skin of the head is cool and pale, we may conclude that the intra-cranial arteries are admitting but little blood; but the converse, probably, has many exceptions. The state of the eye is, perhaps, a more sure guide than that of the skin. A red, injected, eager eye can scarcely imply anything else than an hyperaemic brain; and a pale, dead, white languid eye almost certainly indicates the reverse. The state of the urine may give valuable information. Pale, copious, low specific gravity urine will surely coincide with an absence of, arterial hypersemia; while scanty, red, lateritious, dense urine will invest the cerebral symptoms with an opposite meaning. It is scarcely necessary to refer to the pulse, except to that of the carotid. If this is open and bounding, it indicates that the arte- ries are uncontracted, and admitting a full current of blood. Of course, the reverse would not necessarily imply cerebral anaemia, any more than in peri- tonitis the small, wiry pulse implies an absence of inflammation. Panting, hurried, or irregular respiration (the lungs being healthy) would point towards anaemia. The state of the pupil is so much controlled by that of the brain, as also indeed by that of the cord,* that its indications are not reliably definite. An excited brain or a depressed cord will produce a contracted pupil, or vice versa; though in medium states I think a contracted pupil generally coincides with contracted cerebral vessels, and a dilated with un- contracted. The treatment of anasmic states of the brain is sufficiently evident if the anaemia be general; the only needful caution being '■'■ festinare lente :'' that is to say, as fast as the weak and hypergesthetic nerv- ous centre will permit. Good air and good nourishment, and suf- ficient rest, are, of course, essential ; and for medicines, steel wine, citrate of quinine and iron, carbonate of iron, and cod-liver oil, will generally do good service. In cases where the digestive power is feeble, the lactate of iron, or fer reduit, will probably be more easily assimilated than the more common preparations. Rennet wine may be recommended to promote the digestion of azotized food. Where the anaemia is partial the object of treatment must be either to stimulate the languid brain moderately, or to prevent and allay arterial spasm. This subject will be considered under the head of epilepsy. For the following case I am indebted to the kindness of Dr. H. C. Stewart, whose correct diagnosis deserves great praise : — No. 4. — A general oflScer, aet. 60 years, who had been with our peninsular army and at Waterloo, and subsequently with the army of Don Pedro in Portugal, has had frequent attacks of intermittent fever, and during the last twenty years has suflPered from spasmodic asthma. Dr. St. was sent for ' Dr. Fraser'a paper on Pbysostigma Venenos,, Edin. Med. Journ. July, 1863. CEREBRAL ANEMIA. 69 in a great hurry, and found on arrival that his patient had lost all power over the left side, and had very partial sensation. The muscles of the face on the aflFected side were all relaxed, while those on the opposite side were rigid and drawn. His tongue when protruded was also drawn to the opposite side. He had great difficulty in swallowing his saliva, and his speech was imperfect. His urine was constantly dribbling away from him. B. opened three hours before this attack. There was considerable difficulty of breath- ing. Consciousness was retained, and but for the difficulty of speaking he would have answered questions correctly. Left pupil contracted, right mo- bile. Pulse 100, weak and small. Skin hot and dry; thirst; tongue coated thickly. On inquiry St. found that he had had similar attacks before, for which he had been bled and mercurialized ; that he had also had frequent attacks of intermittent fever, and spasmodic asthma. This in- formation led him to believe that the prostration of the nervous power might be dependent upon some miasmatic poison, particularly as he had recently been staying near Woolwich. He gave therefore six grains of quinine, and some warm drink. About forty-five minutes after St. learned that he had had a very slight rigor, which was followed quickly by heat, and almost in- stantaneously by profuse perspirations, while as the attack passed off the symptoms of hemiplegia subsided. For a week afterwards the ague recurred every other day, and with it the hemiplegia, but in a slighter degree. The disorder yielded to quinine. Since then he has had one other attack in every respect similar, but less severe Remarks — There can be little ques- tion that the phenomena in this highly interesting case were produced by^ spasm of the cerebral arteries, which was so complete on one side as to prevent the nervous centres from functioning. Such spasm of the arteries is constantly present in the cold stage of ague to a greater or less extent, and may be, as in a case I shall subsequently relate, sufficient to obliterate the radial pulse. The symptoms produced by one-sided cerebral embolism are very similar, but the record of the case makes it perfectly clear that no morbid cause of this kind was in action. The paralysis of the sphincter vesicae shows that the cord must have been affected to some extent, probably in the same way as the brain. It is worth remarking that the facial nerve was palsied on the same side as the limbs according to the usual^ but unex- plained, event in all hemiplegia. The following remarkable history is quoted by M. Bailly^ from Wirtensons Memoirs on Opium: — , No. 5. — A lady of distinction was attacked at 11 P.M. with fever, attended the next day with continual nausea, and vomiting of all food. After a small dose of tartar emetic remedies were resorted to, to relieve the vomiting, and with advantage. But the second night the fever returned at 11 P.M., and scarcely had the patient complained of feeling ill, when she lost the power of speech and consciousness. Hoffman of Munster, who happened to be at hand, was summoned. He found her speechless and in a kind of sopor, her eyes open and fixed, her limbs stiff, as in catalepsy. Her pulse was small and intermitted frequently, and her breathing was difficult. In short she had a well-marked soporous intermittent fever. All who were present feared that she would die speedily. In such cases eminent authorities advise emetics, irritating enemata, or blisters, and stimulants, but Hoffmann, who * Bailly — Traite de Fievres Intermittentes, p. 436. 60 CEREBRAL ANEMIA. had no confidence in such measures, whose inutility he had often experienced, followed a very different method. It was not the case to temporize, and in order to save the patient it was urgent to have recourse to effectual means. What remained then to be done? — try the administration of opium. But how could one venture to counteract an unnatural sleep with a remedy which causes sleep ? These considerations did not weigh with this physician taught by experience. He poured into the patient's mouth ninety-five drops of liquid laudanum, and he saw that she swallowed it. After the lapse of a few minutes the pulse was developed, and the breathing more free, and in less than half an hour the lethargy was dissipated, and the danger past. The pulse was full, the limbs had regained their suppleness, the patient regained consciousness and began to speak. Febrile heat succeeded, and afterwards sweating concluded the paroxysm. The next day bark was ordered to prevent the return of the disorder, but the stomach rejected it in every form. Enemata of bark were ineffectual, for at the same hour the next night the paroxysm returned and with the same alarming symptoms as before. The laudanum was given again successfully. The next day the stomach was still intolerant of bark, and a third fit was apprehended. On the suggestion however of the husband, the laudanum was given one hour before the time of recurrence ; it did not prevent the paroxysm, but it deprived it of the sopor and the alarming symptoms. After it was over the patient was able to take a vinous infusion of bark, and was soon cured. liemarks. — The correct reading of this most interesting case is I think similar to that of the prece- ding. The soporous symptoms came on at the onset of the paroxysm in the cold stage, at the time when arterial spasm is prevalent. They were removed and obviated by a powerful sedative, which we must presume to have acted on the over-excited vaso-motor nerves, and to have thus quelled the spasm. As the blood-flow returned to the encephalon its functions were restored. Trotter's experience of the good effects of opium given at the commencement of a paroxysm is quite in accordance with the above history. He found the pulse, from being weak, quick, and sometimes irregular, become less frequent, full, and equal ; an agreeable warmth was diffused over the whole frame, and every unpleasant feeling vanished. This action of opium is analogous to that which it exerts in cases of renal and hepatic calculus, and spasmodic stricture of the urethra, where it seems to relax contracted muscular fibre. I am well aware that it has been thought even more efficacious in the hot stage of ague, and that it has actions apparently of a contrary kind. These points will be hereafter noticed. It need scarcely be stated that the admin- istration of opium would not be suitable to every kind of soporous inter- mittent. If the coma depended on hyperaemic congestion it would be of course contra-indicated, at least in a full dose. It may be remarked with regard to the view I maintain as to the action of opium (v. remedies), that there is nothing inconsistent with it in supposing that a stimulant may cause relaxation of existing spasm, as in Dr. Salter's cases of asthmatic paroxysm arrested by alcohol. ANEMIA OF THE SPINAL CORD. 61 CHAPTER IV. ANiEMIA OF THE SPINAL CORD. We are chiefly indebted to Kussmaul and Tenner for any accurate knowledge on this head. They tied both subclavian arteries close to their origins in several rabbits so that the blood was conveyed to their brains solely through the carotids. They then compressed the arch of the aorta so that all afflux of arterial blood to the trunk of the body was cut off. The results are described as follows. Respi- ration becomes at once slower, and gradually in the direction from back to front weaker and weaker. The hinder part of the body soon becomes completely paralyzed, while the fore-legs are only partially so. In most of the aftimals paralysis of the hinder part of the body came. on without any convulsions. In three of them a short slight trembling preceded ; whilst these trembling movements were in one case only somewhat more rapid, resembling those occurring in para- lysis tremulans, and lasting for some seconds. Within a few seconds, or at most within from one to one and a half minutes the paralysis of the hind legs was complete. Peculiar movements similar to those witnessed in chorea are regularly observed in the fore-legs some time after tying the arch of the aorta. It is not at first clear whether these movements are voluntary, or are involuntary convul- sions: the latter however is found to be the case. They are fre- quently repeated, and are produced by a reflex act when the legs are touched. They gradually cease as life becomes extinct. Respi- ration ceased in from eight to eighty-one minutes after the last con- stant compression. The heart stopped beating in from eight to twenty minutes after the last breath. Consciousness appeared but little disturbed up to the last moment. In one experiment the sub- clavians were tied, and the aorta compressed, which produced almost immediately complete paralysis of the hind and partial of the fore legs. The carotids were now compressed, whereupon a violent epi- leptic attack ensued within a few seconds, but ceased on removing the compression from the carotids. This experiment puts in a clear light the part which ansemia of the encephalon plays in producing general convulsions, and shows that anaemia of the spinal cord is marked more by paralysis than by convulsion. Such being the results which experiment teaches us we may look for when anaemia of the cord exists, we have now to inquire how far we are likely to meet with this condition as an actual morbid change, and how far we are to recognize anaemia of the cord as a vera causa 62 ANEMIA OF THE SPINAL CORD. of disease. The mode in which the cord is supplied with arterial blood, viz , by a succession of small arteries entering the vertebral canal through the intervertebral foramina to anastomose with the anterior and posterior spinal derived from the vertebral, makes it less likely that it should be deprived of blood by constriction or ob- struction of its vessels than is the case with the encephalon. It is not very likely that a large number of small arteries would become and remain constricted simultaneously, and if only a few remained open they would supply blood to the tracts of capillaries. The cases where it seems to us most probable that a paralysis may be dependent on anaemia from arterial constriction are those where the affection ensues paroxysmally apparently in connection with mala- rious fever. Romberg relates a case of this kind where motor par- aplegia occurred according to a tertian type, disappearing spon- taneously. After the due administration of quinine the paralysis ceased to return. M. Bailly describes how, during his stay at Rome, when he was evidently under the influence of malarious infection, he experienced every day about three or four P. M. an extraordinary weakness of the legs, so that he could hardly get along, and was obliged to use his arms, which were unaffected,* to pull himself by the banisters up stairs. He was cured of this symptom by quinine. The following case, for which I am indebted to my friend, Mr. Moullin, was probably of the same kind: — No. 6. — H., aet. 45, labourer, was seized July 9th while at work with violent pain across the loins and with numbness running down the legs. The urine was retained so that he could not pass it, and there was involun- tary discharge of feces. When first seen he was lying on his back at full length, the toes pointing straight out, the skin cold, the legs paralyzed and insensible, even when pinched with the nail. He was quite unable to stir. No pain or disorder elsewhere. Quite conscious. Ordered an enema of turpentine with aloes, and calomel gr. v + pulv. jalap, co. gr. x. After the enema and purge had acted freely the limbs still remained powerless ; the pain continued, but was relieved by a croton-oil liniment. .July 11th. Quin. disulph. gr. x ter die. The next day sensation returned, and the next he could sit up in bed. In a week he walked to the dispensary, and soon after was quite well. The record sufficiently proves that no organic disease existed in this case, the suddenness of supervention and the speedy recovery are quite unlike simple or direct paralysis of the cord, the non-suc- cess of the purgatives and the good effect of quinine negative the existence of inhibitory irritation, so that j)ar voie d' exclusion we are almost obliged to refer it to anaemia from arterial spasm. I have before recorded a similar case where hemiplegia ensued in a like way, and it does seem to me most probable that such cases depend on arterial constriction, principally because we have pretty certain evidence that at the commencement of an ague par- oxysm the involuntary muscles as well as the voluntary are thrown into a state of abnormal contraction. These instances are, however, very rare, and we think they afford no sufficient warrant for extending the same view of causation to all HYPEREMIA OF THE BRAIN. 63 instances of so-called reflex paralysis. It is worth remarking that general anemia suflficient to produce complete loss of vision does not cause paralysis, v. Gooch's case of fatal flooding. The results of the habitual use of ergotized grain as food are not very favour- able to the view of permanent paralysis being occasioned by anaemia. Dr. Brown-Sequard states indeed that ergot produces a contraction of the bloodvessels of the spinal cord and of its membranes, and, therefore, diminishes the amount of blood circulating in these organs. If this be so, we should certainly, on the above view, expect to have paralysis as a much more constant and early symptom than it ap- pears to have been. It does not seem to have occurred in the earlier period of the affection, but to have succeeded to severe spasms aff"ecting the limbs, and producing even trismus and opisthotonos. Violent convulsions and tetanus are produced by ergotism as well as paraplegia. I have given tr. ergotge 5ss ter die for more than a month in a case of proptosis, &c., without observing any efl"ect which could be ascribed to anaemia of the cord. Of course, a relative ansemia may be produced without materially impairing the functions of the spinal centres. Just as the skin of the fingers retains much of its sensibility, even when the supply of blood is much di- minished, so it will be with the cord. On the whole, it appears to me, that we have no suflficient grounds for regarding spinal anaemia as a pathological state which we are likely often to meet with. It is probable that in cases of paresis which we shall presently consider more or less of anaemia may exist, but this is not the primary con- dition, and does not rule the treatment. In the treatment of any case of supposed spinal anaemia from arterial spasm, the moderate inhalation of chloroform, friction with stimulating liniments to the spine, the administration of quinine with diff"usive stimulants and sedatives, and a prolonged warm bath would probably be the most efficient remedies. CHAPTER V. HYPEREMIA OF THE BRAIN. By this term we understand an increased flow of arterial blood to the encephalon. This true hypersemia should be distinguished from venous congestion, which is common enough in the closing periods of various diseases, and at post-mortem examinations, but is rarely the object of treatment, and in its action upon the brain approaches much more to anasmia than to true hyperaemia. The common varicose ulcers of the legs afford proof how unfit stagnating venous blood is to nourish the integument, and it may well be imagined 64 HYPEREMIA OF THE BRAIN. how much moi*e susceptible a tissue, of so high an order as the hrain, will be of the deprivation of its proper nutrient and stimulant. With venous hyperaemia we have here, therefore, nothing to do. Of arterial we have first to remark that it may be either physio- logical or pathological. The first, when it is subordinate to the functional power of the nervous tissue, and ministers to its activity ; the second, when it surpasses this limit, and becomes excessive. To quote a sentence from the Manual of Patliology, p. 81 : " In the one case it supplies a want, in the other it imposes a burden." The very same amount of blood-supply may be either beneficial or injurious, according to the vital quality and condition of the cerebral structure. A weak and irritable organ will be oppressed by that which only supplies the necessary pabulum to the more active life of the stronger. When our brains are jaded and Aveary with work, we find that we gain little by increasing their blood supply with vinous stimulants, and that repose is essential to enable the organ to regain its power. When, however, there is less exhaustion we are familiar with the invigorating influence of wine on the mental faculties. Pure cerebral hypersemia, considered apart from primary cerebral excitement, is by no means very common, at least in this country. Theoretically, it requires for its production increased action of the heart and relaxation of the contractile coats of the cerebral arteries. It is mostly in certain malarious fevers that we find these conditions existing. In a case of double quotidian paroxysm under my own care the patient, a male, aged 46, became quite delirious in the fever, "singing and quite out of his mind." The disease soon yielded to quinine. Copland describes the symptoms of the period of reaction as consisting of flushed face, tumid features, prominent, red, and watery eyes, and pain of head attended by a feeling of distension and throbbing, often passing into delirium. Ranald Martin writes of the remittent fever of Bengal during the stage of reaction : " The blood-current, previously oppressed, becomes now hard and quick, ranging from 110 to 120 pulsations in the minute, and the force and frequency of the circulation through the brain, superadded to the already disturbed condition of the nervous func- tions, give rise to confusion of ideas and loss of mental control, amounting occasionally to actual delirium." Such is the hyperseraia that he states his life was only preserved by a profuse hemorrhage from the nose during the height of the first two paroxysms in a severe attack of jungle fever he underwent. He cites from Dr. Henderson a most proving history to show how powerfully the cere- bral congestion, occurring during remittent fever, tends to issue in apoplectic extravasation. So often did the one terminate in the other that it was "hard to draw the line between them." It is highly probable that in these fevers the hypersemia is both greater and more injurious because of the impaired state of the nerv- ous force in the brain which is depressed by the primary action of HYPEREMIA OF THE BRAIN. 65 malaria, the original cause of the disease. Convulsions do not seem to be a usual result of this cerebral congestion, neither of the authors above quoted mention them. Bailly, however, seems to have observed numerous instances at Rome of intermittent fever which he calls "convulsive." The motor disorder showed itself, however, more as tonic contraction than clonic, and there was no spasmodic closure of the glottis. The following instance affords a good example of severe cerebral hjperaemia passing into actual meningitis. No. 7. — J. C, set. 51, admitted July 18th. — He was furiously delirious,, so that it was necessary to confine him. His pulse was strong and vibrating, but uncountable at first from the continual movements of the arms and body. Two hours later it was 124. The forearms were tensely flexed at an acute angle on the arms, and could not be extended without causing pain to the patient by the attempt. The jaws were firmly closed, the muscles of the lips in continual motion, as were also the lower limbs. Sensibility of surface not impaired. Epigastrium tender. Tongue dry and red. He continued in much the same condition till his death, July 20th. P. M. The arachnoid was thickened, and of brown red colour; the vessels were so injected that their minutest ramifications could be traced. At the posterior part was a false membrane saturated with the red colouring matter of the blood. The arachnoid of the cerebellum was in the same state. The gray substance of the brain was of a remarkably deep red. The vessels of the corpus striatum were injected. Spleen enlarged and much softened. Traces of former in- flammation of the stomach, and recent of the intestines. The distress occasioned by cerebral hyperasmia varies much ac- cording to the condition of the nervous centre. When this is highly sensitive and excitable the suffering may be great. Dr. Williams (C. J. B.) narrates the case of a gentleman subject to attacks of de- termination of blood to the head, which caused him so much suffer- ing and loss of moral control, that he cut his throat to destroy his life. Whilst recovering from the wound attacks came on first with heating of the carotids, then with flushing of the face and head, suffusion of the eyes and feelings of distraction in the head. A writer in the Journal of Psycholog. Med. (Jan. 1863, p. 50) says : " Even in healthy persons, or persons of plethoric habit, this deter- mination of blood may occasion transient delirium, with various signs of encephalic disturbance, such as extreme sensibility to light and sound, restlessness, pain in the head, and visual hallucinations. A flood of distorted ideas flows through the mind, and overwhelms it ; bewilderment and incoherence follow, and for the time being the patient is to all intents and purposes maniacal." Causes. — Hyperaemia of the encephalon will be induced by all stimulating agents which act directly on its tissue, and excite it to increased functional activity. The chief of these are alcoholic liquors ; small doses of opiUm and camphor have a similar effect. The hyperaemia thus produced is secondary. Various conditions 5 66 HYPEREMIA OF THE BRAIN. causing paresis of the vasomotor nerves of the cerebral arteries •will also give rise to hypersemia, which in this case is primary and pathological. It is no uncommon thing to meet with persons who flush very much in the face after a meal. A lady under my care suffered so much in this way, her face and neck becoming of a deep red, that she was unable to dine out. She was of a highly sensitive temperament, and had occasionally some choreic symptoms. Mr. Langston Parker, in his excellent work on the stomach in its morbid states, relates (p. 258) the case of a lady, who when placed under his care had recently recovered from hemiplegia of the right side, but con- tinued to have pain and throbbing in the head, thirst, flushing of the face, and occasional numbness of the limbs. The head was continu- ally hot, the seat of severe pain at the vertex with occasional violent and sudden darting pains through it, which made the patient scream out ; the carotids and temporal arteries throbbed violently, and the pulsations were seldom less than 100 per minute. The epigastrium was the seat of a violent beating, was full and hot, exceedingly tender on pressure, and the seat of internal pains shooting into the hypo- chondria, where she had alsp fixed uneasiness. The stomach and intestines were become so morbidly sensible to impressions, that everything she took produced pain, sickness, and very frequently vomiting; there was constantly an intensely acid taste in the mouth. The patient had previously been recommended rich diet and stimu- lants. She was now treated with a few leeches to the epigastrium, and a nightly mercurial aperient ; which brought away at first pitchy stools. Her diet consisted of farinaceous food. In a week she was well. Several other interesting cases of a like kind are recorded. Mr. L. Parker seems to consider that the irritation of the stomach Was directly conveyed to the brain, and set up there a similar con- dition. When, however, we consider that the only direct connection of the stomach with the brain is by means of the pneumogastric nerves, which are implanted in the medulla oblongata as their centre, and that there was no special disorder of the respiratory function, we shall, I think, be inclined to admit that the gastric irritation affected the brain in a different way. This probably consisted in a morbid impression being conveyed by the sympathetic nerves of the stomach to their ganglia, and thence to the vaso-motor nerves of the cerebral arteries which in consequence became dilated, and thus hypersemia ensued.^ The vaso-motor paresis, in such cases, is of the inhibitory kind explained at p. 22. The extensive diffusive character of the cerebral irritation, in these cases, and the non-pro- duction of organic disease, at least for a long time, indicate pretty clearly that the morbid action is not actually located in the cerebral tissue itself. In not a few cases determination of blood to the head is dependent on a primary state of paresis in the nerves of the cere- bral arteries. ' The record shows that the carotid and temporal arteries were paralyzed. HYPEREMIA OF THE BRAIN. 67 It is a very curious and important fact, which is mentioned by Kussmaul and Tenner, and which would not, I think, have been an- ticipated a priori, that releasing the carotid arteries from compres- sion causes intra-cranial hypersemia. It almost seems as if the nerv- ous tissue by the temporary deprivation of blood was brought into a state of excitability, which induced it subsequently to attract the blood with more force. Or where the arteries have been occluded by a spasm of their own circular fibres it may be presumed that this as it yields is succeeded by a state of paresis and dilatation. The following case exemplifies this : — No. 8. — A merchant, set. 65, seen in consultation with Dr. Barrett, Oct. 10th, 1861. He had in July a first epileptoid seizure preceded for some hours by hemiplegia, which passed off with the fit. A second attack occurred on the morning of the 10th ; he lay in coma till the morning of the 11th, and was gradually recovering the following evening, but not yet wholly conscious. The circulation after the fit at first was depressed, but by the evening it became very active in the scalp and ears, which were red and hot, and did not give a pale spot on pressure, not even for an instant, after the compression ceased. On account of the manifest determination to the head, and the danger of effusion, ^iv of blood were taken by C. C; the night of the 10th, he had also calomel, and enema terebinth. The urine after the attack was free, highly albuminous, not high-coloured, sp. gr. 1022, deposited lithates on standing. 14th. The stupor has now nearly passed off, though his mental faculties seem rather torpid. Has passed two very dark scybalous motions. Tongue clean. Heart rather enlarged, otherwise apparently nor- mal. Lungs healthy. His legs have been enfeebled for some months past ; he walks like a person crippled by rheumatism. Has been generally very healthy. May 9th, 1862. He has remained pretty well till two or three days ago, when he had an attack of stupor without convulsions. He was relieved immediately by mild purging, and is now tolerably conscious. Pulse of apparently good force, large, Grets weaker in walking. Urine continues constantly albuminous. Some months after he had another attack, and died comatose. Remarks. — This case is one of great interest in more respects than one. It illustrates very well the occurrence of coma together with an over-active state of circulation as a sequel of epilepsy, and the dan- ger that this hyperasmia may occasion if excessive. It also indicates the probability that hemiplegia may in some instances depend on a similar patho- logical condition to that which gives rise to convulsions. It seems for instance tolerably certain in this case that the hemiplegia, which disappeared so speedily, depended like the convulsions on closure of the cerebral arteries; only that during the palsy a different set of vessels was affected, perhaps those of one hemisphere and one corpus striatum only. Subsequently the arterial spasm became more general, and involved the vessels of both sides, and those of the excitable districts. In the attack of stupor without convul- sions the arteries of both hemispheres were probably constricted. The renal affection, I believe, only so far contributed to the nervous disorder that it rendered the blood less fit for maintaining healthy nutrition, and so induced a state of weakness and excitability of the nervous centres. The loss of an autopsy is much to be regretted, still it seems tolerably certain from the absence of permanent morbid phenomena that there was no material organic change, except perhaps in the lower part of the spinal cord giving rise to the paresis of the lower limbs. 68 HYPEREMIA OF THE BRAIN. Malaria is of course the great cause of cerebral hypersemia in inter- and re-mittent fevers. This complication is not so frequent among us as it is in tropical climates ; it is nevertheless occasionally met with, and according to my experience most often among children in that form of disorder which I have termed malarioid remittent. Exposure of the head to the rays of a powerful sun seems certainly to cause in some cases cerebral hypersemia. Dr. Murray, quoted by Sir R. Martin, thinks that this effect is to be distinguished from that of the same temperature in the shade where the action of the heat is more general. In this view I quite concur. The phenomena in the latter condition seem to be essentially those of extreme ner- vous exhaustion, which we shall subsequently examine. Dr. West mentions an instance in which exposure to the sun's rays clearly induced an inflammatory state of brain. Burns, as in a case I shall presently relate, sometimes have a similar effect. The injury to the skin causes inhibitory paralysis of the cerebral vessels, from which hypersemia results. The poison of the exanthemata before the eruption appears, i. e., before it directs its action to the vaso- motor nerves of the skin, often causes considerable cerebral conges- tion, apparently from direct irritation of the brain. Dental irrita- tion in children is a frequent cause of cerebral hypersemia, the head being hot, the anterior fontanelle prominent and pulsating strongly, the brows knit, and the skin febrile. All these symptoms subside on the tooth passing through the gum, or sometimes on effectual lancing. I have seen the flushing of face subside in a few minutes after the gums were lanced in a child who had just had an attack of convulsions succeeded by stupor. In this case it seems to me certain that the convulsions and the cerebral hypersemia were caused by the uprising tooth (a posterior molar); the question is how. The convulsions probably depended on the increased excitability of certain parts of the brain affected by the irritation. The hypereemia from its involving the extra- as well as the intracranial parts, and from its speedy subsidence on removal of the exciting cause must have been owing to inhibitory vaso-motor nerve paresis. The morbid changes produced by cerebral hyperasmia are well exemplified in the following case. No. 9. — J. R., m., set. 16, ad. Nov. 11th with a burn of the third degree affecting the lower part of his abdomen, and the upper and inner part of his thigh, as well as the genital organs. The shock was severe. Pulse feeble. Respiration slow. Pain severe at night. On the 13th an erythematous eruption appeared on the chest and abdomen closely resembling that of scar- latina ; the tongue also was in a very similar state to that observed in this fever. He passed two very delirious nights; on the 15th the eruption became more dusky, the hands and feet cold, and he sank at 2 P.M., having been perfectly sensible before death. At the autopsy there was found extra- vasation of blood under the scalp, and effusion of blood between the dura mater and the bone. All the membranes of the brain congested. Effusion of fluid beneath the arachnoid. The white substance displayed numerous HYPEREMIA OF THE BRAIN. 69 puncta vasculosa. The ventricles did not contain an abnormal quantity of fluid. The lungs and all the viscera were congested. Brown-Sequard's experiments have shown that the various remote effects produced by burns are brought about through the intermedium of the spinal cord, which he regards as reflecting the irritation from the burnt part of the secondarily affected organs. In my opinion the remote action of the burn is not on the tissue of the organs themselves, but on the vaso-motor nerves of their blood- vessels, which in consequence of the morbid impression are paralyzed. It seems in this case, as not uncommonly happens in such instances, that the textural quality of the minute vessels was impaired so that extravasation of the blood ensued. Paralyses of vessels are, I think, not unfrequently asso- ciated with such loss of retentive power in the capillaries. Common epis- taxis with its cure by putting a cold key down the back affords an example where a like state is remedied by the tonic effect of cold acting on vaso-motor through afferent nerves of the cord. The resemblance of the eruption to that of scarlatina in this instance was very close, the chief difference being that the face was but little affected. The mode of causation in both I believe to be the same. It seems distinctive of reflex vaso-motor paralysis that the hyperaemia it produces is diffuse, while that of tissue irritation is more local- ized and tends more to exudation and suppuration. The treatment of cerebral hyperaBmia must depend very much on the view taken of its causation. If it depend on direct irritation as on heat, exanthematous poison, alcohol, &c., it will be desirable if the strength of the patient permit, to deplete locally, apply cold, and promote afflux to the feet by hot mustard pediluvia. Internally ■we may purge, or employ Graves' tartar emetic and opium treatment, or repeated doses of colchicum. If the hypergemia depend on para- lysis of the vaso-motor cerebral nerves from malaria, or other influ- ences, depletory and counter-irritant measures must be adopted to stave off the risk of hemorrhage or eff'usion if it appear imminent, and in the remissions nerve tonics, especially quinine, must be admin- istered to remove the primary paralysis. If the vaso-motor paresis depend on a remote morbid impression, this must be mitigated or removed if possible. For this in cases of burns opium is probably the best internal remedy, and a continuous warm bath the best ex- ternal. Hebra^ relates that he kept a patient who was severely burnt continuously immersed for 21 days with the best effects. Another patient with a frightful and inveterate pemphigus was kept in the bath 100 days with the best results. The soothing influence of moist warmth takes off the depressing inhibitory influ- ence. Mr. Windsor's experience is to the same effect (v. Syd. Soo. Year. Book, 1863, p. 205). The following cases of hypersemia are of interest:— No. 10. — E. L., f., get. 16, ad. Aug. 20th. Ill three weeks; complains of a burning flushed state of both sides of face, extending to the head, which puts the head into much pain, makes it feel hot. She is obliged by attacks • "London Med. Rev.," Jan. 1860. 70 HYPEREMIA OF THE BRAIN. of this kind to go to bed every day. They occur indifferently at all tinaes of the day. She sleeps well at night. Digestion weak. Tongue clean. Bowels open. Pulse soft. kShe continued under treatment till November 21st, when she was well enough to be discharged. After she had improved I noticed one day that one cheek only was hot, the other being cold. The remedies employed were strychnia and tr. ferri muriatis, and assafoetida. Tannin with gentian and henbane benefited the digestion, but the disorder was certainly not chiefly if at all of gastric origin. It was a primary pare- sis of the nerves of both external and internal carotids, as evidenced by the juvantia and the general character of the symptoms. It is very evident how a depleting lowering treatment would aggravate such disorder. No. 11. — Gh., m., aet. 55, of short, broad make, very short neck. Has been suffering two or three years with an uncomfortable sensation in his head, most felt on the right side, but extending all over it, not worse on lying down, but much increased by a warm close atmosphere, and relieved by the open air, and by cold bracing weather. Seems to be of excitable tem- perament. If he goes to church can only stay for about an hour, after which he gets so excited and irritable about the head, that he is obliged to come out. His bald scalp flushes with blood while I speak to him. Head apt to be hot, when he is better is cold. Has rushing noises in the head. Feels sometimes weak in his legs, and is relieved by a purge of blue pill + scammony -f jalap. Is not subject to rheumatism or gout, nor is the latter in his family. Urine free and natural. Heart's sounds and position normal. No indigestion. Pulse 75, of moderate force. He was ordered nitric and hydrocyanic acids with cascarilla infusion ter^ and quinine, tannin, and henbane in a pill his die. This treatment proved decidedly beneficial ; he found more inclination for mental work, and less tendency to procrastinate. In the latter case it was remarkable Jhat the patient did not find the uneasiness in the head increased by lying down. The same was observed in another patient, whose symptoms were very similar, the carotids throbbing strongly, but who stated that his head was re- lieved by the recumbent posture. In one of the epileptic series the same is mentioned. It is not easy to explain this peculiarity, per- haps it may depend on the heart's action becoming less in the re- clining position. Even when the cerebral hypersemia is of traumatic origin the same is sometimes the case. No. 12. — J. H., m., get. 16, ad. Sept. 13th. Ill seven days, was struck by a ball on the head the day before he became ill. He has great pain in the head, throbbing in the temples, nausea and loss of appetite. Head hot. Has not more pain on lying down. With eight leeches to the temples, a blister to the neck, some Gray and Dover's powder he soon got well. It is clear that there was direct irritation of the brain in this youth, yet he did not need to keep his head elevated. On the other hand, in the following instance the peculiar attacks seem to have been promoted by the recumbent posture. H. H., get. 26, a sufferer from sub-acute rheumatism, but rather inclined to plethora, has seizures which he describes as follows : They begin with a sense of fluttering SPINAL HYPERiBMIA. 71 at the heart, and a feeling of fright, then all the blood in his body rushes to his head, which throbs violently, and seems full as if bursting. This state lasts five to ten minutes, during which he can- not move at all, tries to move but can't, is however quite conscious. The attack subsides spontaneously. It always occurs at night while he is lying down. It is worth observing that neither in this nor in five or six other cases of cerebral hypersemia were there any convul- sions. In Nos. (10) and (11) the pathological condition was essentially different from what it was in (12). There was active hypersemia no doubt in all three, but in the two first it depended solely or chiefly on relaxation of the arteries, or vaso-motor nerve paresis ; in the last it was the result of irritation of the cerebral tissue, and was produced by a vis a f route. It is evidently a most practical matter to distinguish cases having one origin from those which have a dif- ferent. The treatment must be determined by the diagnosis, and in some cases it is by no means easy. In the case of H. H. I think there ensued at first a spasm of the cerebral arteries, which was followed by sudden relaxation. The afi"ection was akin to epilepsy. CHAPTER VI, SPINAL HYPEREMIA. The spinal cord is evidently very differently circumstanced com- pared to the chief mass of the encephalon with regard to its supply of blood. That furnished to the latter is very abundant, and this large amount appears to be necessary for the due performance of its special functions — a failure or diminution of the supply being immediately felt, while on the other hand an overflow has equally injurious effects. In the case of the spinal cord these variations seem to be of much less moment, and we can by no means point with so much confidence to morbid results produced by them. No doubt the phenomena of meningitis, and myelitis, or apoplexy are evident enough ; but these affections do not come within my plan as they involve actual organic change. With regard to spinal hyper- emia much importance has been attributed to it by various Conti- nental writers of an older date as the cause of numerous morbid phenomena. Frank imputes certain pains of the back and lower extremities, certain sciatic neuralgias, certain species of lameness, divers tremors and convulsive movements, stupor or paralysis of those extremities as well as several epileptic and tetanic phenomena to congestion and distension of the vertebral sinuses and veins (Olli- vier). Ludwig also views the very acute dorsal pains which so often exist in severe intestinal colics, and the pains in the back and limbs 72 SPINAL HYPER-aiMIA. which occur at the onset of fevers as depending on a like condition. Portal explains convulsive and paralytic affections of the extremi- ties occurring in various inflammatory diseases by congestion of the spinal vessels. Ollivier relates the following case. " I exam- ined the body of an individual who had been affected with incom- plete paralysis in the movements of the trunk and extremities with morbid exaltation of the cutaneous sensibility. This paralysis . . . had gradually diminished and was nearly gone, when it again ap- peared simultaneously with a pleuropneumonia. This latter disease made rather rapid progress, and the paralysis was observed to go on increasing till his death ; so that a few days before he died the patient had relapsed into the same state of paralysis with extreme sensibility of the integuments. The upper and lower extremities performed but very feeble and general movements ; respiration was extremely painful, and the movements of the chest were almost im- perceptible. He preserved to the last the free use of his intellects. At the post-mortem we found rather extensive pneumonia and pleu- ritis of the right side ; there existed at the same time considerable sanguineous congestion in all the meningo-spinal veins, which were manifestly dilated. The nervous cords were enveloped in a collec- tion of veins very much gorged with blood, which evidently com- pressed each spinal nerve at its exit from the spine, a circumstance which perfectly explained the phenomena observed during* life." Another case is related (from Dance), the subject of which was a female, set. 31, who a month after a favourable confinement was attacked with formication of all the limbs, which speedily became paralyzed, while sensibility remained. The respiration became difficult and she died asphyxiated on the second day, having been bled twice. A very careful examination showed nothing abnormal in the brain or cord. All that could be detected was some red points on the cut surface of the brain, and slight infiltration of the cellular tissue of the spine external to the dura mater. The organs were all sound. 0. explains the paralysis by the assumption of a congestion, which disappeared after death. This assumption seems to me quite inadmissible, for the death was of that kind which spe- cially ten.ds to increase and perpetuate venous congestion by reason of the impediment to the return of the blood to the right heart. There was just as much reason for finding the venous plexuses gorged in this case as in the preceding, and I must think the ex- planation of the paralysis in both is erroneous. The loss of motion alone cannot be explained so far as I can see by the congestion, as the distended veins would press equally on both anterior and pos- terior nerve roots. Nor can I admit that the cord surrounded as it is by subarachnoid liquid is at all more likely to be compressed at its anterior than at its posterior part, because the former is nearer to the wall of the canal. These cases afford a good illustration how much more prone we are to be impressed by the visible than by the invisible, though the former may be very inadequate to account for SPINAL HYPEREMIA. 73 the phenomena. A case which ended in recovery is given hy the same author. The patient, set. 38, led an active and laborious life, but was habituated to alcoholic and venereal excesses. The latter especially induced a pain in the loins and trembling of the lower extremities. For two months before his attack he had general de- bility of the legs and wandering pains, yet followed the same mode of life. It was not surprising that paralysis of all the limbs, and of the erector spinse muscles should have ensued with some numbness and sense of formication. Venesection was useless, and after the application of twenty leeches to the back the paralysis became com- plete. After four blisters there was some improvement, but nux vomica given in gradually increasing doses was of no avail, and was discontinued, only dry frictions to the spine and to the extremities were occasionally employed. After three months' illness the paraly- sis entirely disappeared. The cause assigned for the paralysis by Ollivier is the recurrence of sanguineous congestion, and increased exhalation of the vertebral liquid. I cannot but think that a more natural and truer reading of the case is that the essential pathologi- cal condition was exhaustion of the nerve-power of the cord, which, with rest, was gradually restored. On reviewing the above cases, which seem to be fair specimens of the kind in question, I cannot but join with Abercrombie in feeling considerable doubt how far spinaPhypersemia (venous) is ever a- cause of failure of the functional power of the cord. Arterial (true) hypergemia we may be sure would (supposing it to exist apart from actual inflammation) lead to in- creased activity of the nervous tissue, such as exists in tetanus and in similar states. It is impossible, however, to separate the effect of the hyperaemia in such instances from that of the agent, as strychnia, which has induced it. Duclaux^ has recently described as spinal congestion various phenomena, which were produced by excessive heat, and which were evidently very similar to those of heat-apoplexy. Patients were suddenly attacked with headache, muscse volitantes, general cyanosis, and derangement of the digestive functions. Insensibly and in a short space of time there occurred a failure of strength in the limbs, substances held in the hands were permitted to fall listlessly to the ground, and the gait became uneven and irregular ; there was giddiness and frequently syncope. Pain was commonly complained of at different parts of the vertebral column. Antiphlogistic and purgative treatment was usually suc- cessful, especially mercurial friction along the spine. Blood-letting was seldom required. The symptoms in these cases appear to me to have depended much more on a state of paresis, of exhaustion and enfeeblement of the nervous tissue than an active hyperaemia. The morbid influence of heat is invariably depressing. It is very possible that active hyperaemia did occur secondarily to some amount, and the results of treatment go to prove it, but I cannot view this as the primary morbid change. J Lond. Med. Gaz., Aug. 1860. 74 CEREBRAL PARESIS. I conclude this subject with expressing my entire concurrence in Kussmaul and Tenner's 22d conclusion, and in extending it to the spinal as well as the cranial cavity. The last few hours of life must almost invariably induce considerable alterations in the distribution of blood, and we know that even after death the position of the corpse has a very considerable influence. CHAPTER VII. CEREBRAL PARESIS. By this term I mean a state in which without demonstrable organic change there is greater or less enfeeblement of the func- tional power of the brain. Perhaps the simplest instance of it is when after much exertion of mind or body we feel incapable of any sustained mental effort. By repose the functional power in case of mere fatigue is early restored, but in various morbid states repose alone is insufficient. Prolonged extreme mental exertion may in- duce such a degree of paresis as to constitute dementia, and the same may result from any severe mental shock. The non-dependence of this state on actual organic alteration in some cases is evidenced by the temporary restoration of the intellectual power under stimu- lants, as wine. Paresis may affect any or all of the cerebral func- tions, either the intellectual, or the voluntary motor, or the sensory. The liability to paresis will vary much according to the original vigour and endowments of the individual, and also according to the wear and tear to which he has been subjected. The phenomena of cerebral paresis are of course very varying, but all bear the stamp of debility, mingled it may be in certain cases with indications of abnormal excitability. In many instances the phenomena of primary cerebral paresis and of general anaemia will be very similar, the anaemia in fact being the cause of the failure of power. Paresis, however, is most often quite independent of anaemia. In some cases paresis of the brain seems to be the reflex of inhibitory irritation. Instead of attempting to give an abstract description of the state in question, I propose to record briefly the leading features of various cases I have met with, which as actual occurrences seem to me more impressive than any general statement. A lady, aged 80, of strong constitution, calm mind, and energetic disposition, had a moderate attack of influenzal catarrh. In this she had the following symp- toms referable to the head. She lay in a dozy torpid state, the stupor being so marked that she could hardly believe she had not taken opium. If she did not get her food when she wanted it she felt as if her understanding were leaving her. Bark and am- monia with wine benefited her, but even some days later, when con- CEREBRAL PARESIS. 75 valescent, she could only lie quite still without speaking or doing anything, and felt as if she had no use of her mental faculties. The pulse was intermittent, but not specially weak. This was an instance of simple paresis of the hemispheres. F., male, of middle age, stout, is attacked suddenly one evening with faintness, giddiness, severe retching and vomiting. He could not stand, and his head felt as if it did not belong to him. He had felt unwell during the day, but the faintness, giddiness, and sickness came on all in five minutes. There was no epigastric tenderness, no headache, no pain, but drowsiness. He could not raise his head, except for a short time when he was sick. In four or five days the sickness had sub- sided, and he was gaining strength, but was only just able to read, and his head was still very apt to be giddy on any quick motion. His tongue was clean all the time, and his pulse not at all weak corres- pondingly to the peculiar debility of the head. Under a tonic treatment he recovered, but it was long before he lost the tendency to giddiness. In this case it is clear, I think, that the brain was affected by a stroke of influenza, which partially paralyzed its action, and perhaps also that of the vagi nerves. There was no indication of cerebral anaemia, the giddiness seemed to be the result of direct debility, which continued for a long time. — R. F., set. 17, male, admitted January 28th. He complained of stupidness, nervousness all over, a great sense of weight at the vertex, and great sleepiness. Functions in fair order. With ammonia, iron, nux vomica, and valerian he was well in three weeks. The cause of the disorder is not clear in this instance, but it is evident that the cerebral func- tional energy was impaired. M. W., set. 8 1, female. She has been ailing with nerve disorder ten to eleven months, has improved much on tonic treatment, but has re- lapsed last fourteen days. She has been at school, and has been over-exerting herself a little. She is silly, irritable, and bad tem- pered in mornings, and then her right arm gets affected with shaking, and her right leg aches, and the foot is everted, so that she cannot walk. At the same time her speech fails, and she stutters. At times she gets quite unconscious; the other day she was so for some hours ; she then is pale, and makes a snoring noise in breathing (paralysis of the velum palati). The unconsciousness is apt to come on when she is tired. Has pain in back at times, but there is no tenderness in the spine on percussion. No ansemia. In this case the general condition was allied to chorea, but there was disorder of the intellectual centres as well as of the motor. — M. H.,set. 11, female. Ill two months, right side is partially paralyzed ; her movements are also unsteady as in chorea; cannot grasp anything with the right hand. Leg dragged ; tongue drawn to one side ; functions in good order. With strychnia, iron, and chloric ether, she got well in less than two months. There can be little doubt, in this case, that the brain was the seat of the disorder from the unilateral character of the affection. The motor centre was weak and irritable, and as it 76 CEREBRAL PARESIS. regained tone and power under the use of the rohorants, recovery ensued. This clearly was a paresis. — J. J., male, set. 17, ill with catarrh fourteen days. Stomach disordered, memory much impaired, cannot be trusted alone ; appears very nervous ; speech impaired and power of holding things in his hands; is ready to fall if at all irritated or startled. Of large lax make. In three weeks he was cured by iron, quinine, and nux vomica, after three mild aperients. — F. F., male, set. 14, ill fourteen days. Seems silly, strange, and very wandering, but answers questions. Pulse slow, weak. No other apparent disorder. Recovered in three weeks with quinine and nux vomica. — L. W., set. 13, female. Health generally good, ill three weeks. Was at- tacked at first, at 10 A. M., by a kind of fit; lost the use of her legs and arms ; her speech was quite altered ; she looked livid ; and, according to her father's account, appeared " taken for death." She did not recover consciousness by the evening of the day on which she was attacked. At the time of her admittance she had in great measure regained the use of her limbs, but still could not dress or undress herself; she often complained of pains in her arms, more in her head. She recovered with iron, quinine, cod-liver oil, and nux vomica in eight weeks. In the last three cases the symptoms indicate that the brain had been affected by some depressing influence interfering more or less seriously with the exercise of its functions. Of the nature of this influence there is no certainty, but it seems a probable conjecture that it is some miasm akin to that which pro- duces epidemic catarrh. The length of time during which the mor- bid phenomena continued makes it certain that they were not of epileptic or syncopal character. Neither is there any indication of their resulting from reflex inhibitory irritation. I have chosen to . record the above instances, not because I think them very unusual, but because their import scarcely seems to be appreciated by prac- titioners generally. It is to my mind a capital fact in neuro-pa- thology, that the great nervous centres are liable to have their functional power so seriously impaired by obscure (atmospheric) causes, apart from any organic lesion, or manifest cause of debility. It is clear that the nervous centres may be vexed and depressed by the same kind of agencies that harass the nerves. They may also become gradually debilitated from various causes till they give way in a sudden collapse. This should be born in mind in dealing with all obscure cases of central aff"ection. Dr. Prichard applies the term leipothymia to certain fits of epi- leptic character, "consisting in a sudden loss of sense and con- sciousness, the muscular system being relaxed, and the patient lying in a state resembling sleep, at the same time without that state of the circulation which is peculiar to syncope." The afi"ection does not appear to be a frequent one. In the only case where I remember to have witnessed it there was no indication of cerebral ansemia, but extreme weakness of the nervous system generally. The following quotation from Mr. Austin's work on General CEREBRAL PARESIS. 77 Paralysis affords a well-marked example of the production of cerebral paresis, of the most complete kind, by remote irritation. The paresis in these cases is of inhibitory character, and is the result of two factors, viz., on the one hand the impaired state of the vis nervosa in the encephalic centre, and on the other the intestinal irritation. That the paralysis is not the result of spasm of the cerebral bloodvessels is apparent from the gradual manner in which recovery takes place in most instances, unlike the complete cessa- tion of the phenomena as soon as a fit of epilepsy has terminated. " A recognized paralytic is suddenly found completely hemiplegic. The fit, which usually happens in the night, is unattended by shriek or scream, and is frequently free from convulsion. It is accompa- nied by semi-coma and suspended utterance, and often announces itself to the attendants or to the sufferer's fellow-patients by loud teeth-grinding, or by the seized person falling out of bed. Then the neighbours find he has fallen because an arm and a leg are powerless. Frequently the paralytic who may have been retained in bed by the well-tucked-in clothes is only discovered to be hemi- plegic when the attendant comes to get him up in the morning. When he comes under medical inspection he is semi-comatose, his utterance is in abeyance, he is quite hemiplegic, but with sensatipn only slightly impaired. If the arm or leg be pinched, vigourous movements of the affected limbs ensue. Though sometimes appa- rently insensible to all going on around him there is frequently a hopeful glimmer of intelligence in the eye. The mouth is rarely distorted, and the movements of the eyeball are more perfect than might have been expected. The pupils are more unsymmetrical than usual. An attendant now administers an injection of eight tablespoonfuls of common salt dissolved in a pint of warm water. In nine cases out of ten, in at most an hour, a copious stool is the result, composed of small, hard, quite distinct rounded lumps. After an evacuation of this kind I have known a person quite hemi- plegic at 2 P. M. recover a free mobility of the arm and leg by mid- night. Usually, however, several similar enemata and their result- ing stools are required before an approach to the ordinary move- ments of the limbs is obtained. Occasionally castor oil, and calomel -f colocynth are employed the sooner to clear out the intestinal tube, or at least the large intestines. The object of these simple remedies is not, by serous evacuations to derive from the head, but, simply to expel the hardened feces, of which the colon is full, and which I regard as the eccentric cause of the seizure. The cause removed, nature aided by a moderately generous diet, will soon restore the affected limbs to their former condition. Such measures as blistering, cupping, leeching, purging, and the like, are not only superfluous, but I believe in the highest degree prejudicial during these seizures. At any rate without their exhibition I have seen nearly weekly rapid recoveries from the completest hemiplegia. Under injections, castor oil, a pill of col. c. calom. in a day or two 78 CEREBRAL PARESIS. the patient's leg begins to move, and his utterance for monosyllables to return. Later the movements of the arm commence, and the memory becomes sufficient to enable him to recognize and name correctly those around him. Day by day the amelioration proceeds ; and I have frequently seen a person, hemiplegic for the first time a week previously, again walking, and with his former gait in the infirmary. Usually, however, two to three weeks may elapse before the patient quite regains his former mobility. During this time all that is required is simply to watch, and gently to sustain the peris- taltic action of the intestines." Dr. Palmer records' the following interesting case, which seems to me plainly of reflex inhibitory nature : — No. 13. — A. B., set. 63, a temperate male, free from rheumatism, gout, or constitutional syphilis; has no teeth, but eats meat. April 4th, 1859, he was suddenly seized in the morning with left side hemiplegia, which was almost complete. His face was pale, he looked dull and bewildered. He was laid horizontal, cold applied to his bald head, and calomel gr. iv given. Marked improvement ensued in two hours, and the bowels acted two or three times. He felt much better, and had regained considerable power over his leg and arm. Six leeches were applied to the temples, salines, and ape- rients given. In four days all paralysis was gone. He remained well for four years except an annual attack of bronchitis. He still ate meat with toothless gums. Early in 1863 he began to have irritation of the diaphragm, and unbearable restlessness and oppression in the early morning. Subse- quently his mind became enfeebled, any trifling business matter threw him into a state of agitation, excitement, and sense of impending death or insan- ity. Then he became the subject of severe nervous dyspepsia. Marked and complete relief was afi"orded by narcotics, but after a few days the effect was lost, and he was worse than before. All this time his tongue was almost perfectly natural, the bowels acted regularly every day, the head was hot, and the temporal arteries pulsated rather strongly. The cerebral irri- tation was justly regarded by Dr. Palmer as the analogue of the past hemi- plegia. It was however unrelieved by a great variety of treatment including repeated aperients, stimulants, and complete rest of mind and body, until, on Dr. Goolden's advice, a larger dose of calomel was given followed by a pow- erful cholagogue of manganese. This brought away a large quantity of very offensive feces, and the patient was permanently and completely relieved. His mental faculties were quite restored. There can be no question that on the second occasion the morbid impressions conveyed from the intestines affected the brain directly, enfeebled and disordered its actings. The state of the circulation in the scalp makes it almost certain that the brain was not ansemic, rather the reverse. In the first attack it is uncertain whether the hemiplegia should be referred to arterial spasm, or to inhibitory ir- ritation. The pallor of the face and the suddenness of the seizure point rather to the former as the more correct view. If this be so, « Lancet, Dec. 19th, 1863. CEREBRAL PARESIS. 79 we must regard the vaso-motor nerves as primarily affected in the first case, the hemispheres in the second. In the following case the cerebral disorder appears to be plainly referable to gastric distress, which acted in the same way as the intestinal irritation in the preceding : — No. 14. — Mr. "W., m., set. 42, seen Sept. 26th. Ill since the previous November, has been unable to sleep at night for a long time until latelj, has lost flesh and got rather weak. Has very marked tenderness in the region of the stomach, particularly at the epigastrium, which has increased lately, and pain after food. The uneasy feeling in the stomach comes on in such a way at times that he is obliged. to run out, or move about in some way; he feels as if he should go out of his mind. Has had strong suicidal impulse while suffering from the pain. Sometimes gets relief from crying. Says he does not know whether his mind or his body is affected, but strives against it all he can. Has conceived a dislike of his best friends. Does not appear at all hypochondriacal. Is a temperate man, can't take wine or beer, but has been obliged to take several glasses of neat brandy at night to make him sleep; the brandy does not affect his head as it used, but seems to go to the stomach and relieve it. Used to have piles, but not bleeding. Bowels regular. Pulse weak, quick. No tumour in stomach. Liver and spleen not enlarged. Lips rather anaemic. Heart's sounds normal, except the second, which is not quite pure. Urine generally clear, deposits a very few small oxalate of lime crystals. Has much flatulence. He had a mor- phia-dressed blister to the epigastrium, and took a mixture of tr. cinch. + tr. valerian, -f- tr. hyoscyam. + ammon. carb. + inf. valerian, ter die, and ferri carb. saccht. ter die. By Oct. 9th he was decidedly better, sleeping very well; his epigastrium was almost quite comfortable, he could take a beefsteak very well. The causes of paresis of the encephalon are all such as produce nervous exhaustion. Excessive mental toil, monotony, unhealthy malarious climates, oppressive heat, venereal excess, and influenzal miasms, are the principal. The possible dependence of the prostra- tion on some inhibitory irritation should be borne in mind. The injurious effects of overwork of the brain are well known. I should not do more than name it here, were it not that I would fain add my voice of warning to those which have already been given. Al- most while I write, a youth is brought to me, whose father is intent on pushing him forward in his studies, unheedful, though a kindly parent, of his son's failing nervous power, as marked by an abdominal neuralgia, pallor, nocturnal restlessness, and a sense of unusual in- capacity for mental exertion. Stern necessity may oblige those who are engaged in the thick of the battle of life to strain their powers beyond what is prudent, but in the case of those who are being trained for the strife all approach to such over-exertion should •be discountenanced. It is sad when early promise of excellence is blighted by inevitable destiny, but much more sad if the collapse must be attributed to our own want of care. The ill effects of mo- notony are best illustrated by the languor, ill health, and sometimes 80 CEREBRAL PARESIS. mortal disease which are apt to ensue among soldiers and sailors when reduced to compulsory inactivity ; while cheerful excitement ha& an almost magical opposite effect. The melancholy chant of • the Count of Toulouse^ expresses no futile apprehension.^ Nature, in her insatiable love of variety, in the changing seasons, and the ever-varying weather, seems to indicate clearly enough the advan- tage of frequent change. All experience of malaria testifies to its specially depressing influence on the nervous system, not to mention the cretins, the inhabitants of malarious districts are spoken of as feeble in body, and spiritless in mind, phlegmatic and melancholy, stupid, languid, and apathetic. The action of heat in producing languor and general enfeeblement of nervous power is a capital fact, and one I have often thought is by no means sufficiently regarded. It is surely a very significant circumstance that an ordinary man can carry, without inconvenience, a heavy overcoat on a cold day, and walk much further and faster thus laden than he could on a hot day more lightly equipped. This surely implies a much greater amount of energy in the motor nervous apparatus in the one case than in the other. A rifleman will tell you that his aim is much more true and steady in cold bracing than in warm relaxing weather. Men endued with great nervous power are capable of enduring heat much better than others. Napoleon, it is said, when in Egypt habit- ually wore his coat buttoned up. The British soldiers in India, in general, bear the fatigue of forced marches under the burning sun of that climate better than the native Hindoos.^ In fact, the stronger and better toned the nervous system is the more capable is it of resisting the enfeebling and enervating influence of heat. This is very well exemplified in the affection termed heat apoplexy, of which I propose here to take some notice. Intemperance, espe- cially in the use of spirituous liquors, predisposes powerfully to this disorder, and so also do close crowding and bad ventilation. On the other hand, temperance, cheerfulness, and the energetic pursuit of duty, have been proved, as in the memorable siege of Delhi, to have a wonderful influence.^ Paley, with admirable wisdom, re- ' "Oh dear, what will become of us? Oh dear, what shall we do? We shall die of the vapours if some of us Can't find out something that's new." J. of Psychol. Med., July, 1863. 2 V. also an instance of the appearance of scurvy among American troops, who were fairly well supplied with fresh food, but who had no active employment, and became homesick and disgusted with the service. Several died of scurvy. Several who were sick began to recover from the moment they were told they should have their discharge. — Amer. Med. Times, June 1st, 1861. 3 Alison's "Hist, of Europe," vol. xvi. p. 71, note. * Sir R. Martin writes, p. 410 of his work : "Officers before Delhi describe them- selves as marching all day in the sun of June, July, and August, and serving in the burning trenches for weeks together; and yet they preserved their health under a tem- perature of 130° or more through temperance to a wonderful extent." Contra, Dr. Barclay states, as the result of his observation, that men whose nervous systems had been injured by intemperance were much more disposed than others to attacks. CEREBRAL PARESIS. 81 commends the manful discharge of duty as the best remedy against "sinkings and oppressions of the spirits." The action of heat, whether it be direct solar, or a simply elevated temperature, is evi- dently the prime motor of heat-apoplexy, as the other causative conditions are chiefly predisposing, though in this respect their in- fluence can hardly be over-estimated. The observable phenomena will vary according to the particular part of the nervous system, which especially succumbs under the morbid influence. In the worst cases where death occurs almost instantaneously the medulla oblongata is probably the focus of morbid action. Death ensues from arrest of the respiratory changes in consequence of the paresis of the vagi, and the lungs are found intensely engorged, even to the production of apoplectic extravasation, while the brain is almost free from lesion. In other cases of slower progress where the dis- order commences with feverish debility in the morning, and termi- nates in stupor in the afternoon, the cerebral hemispheres are more especially affected, their vessels are found exceedingly congested, and those of the lungs less. Assuming the paresis to be primary, cere- bral congestion ensues, according to the well-known law that im- pairment of function is intimately connected with impediment to the free transit of blood through the part. Thus the lungs become congested in apnoea. The circumstance that in the milder seizures the phenomena take the form of fever, either ardent, or remittent, or intermittent, points to the strong probability that in these in- stances the vaso-motor nervous system is specially implicated. I subjoin here the notes of two cases of this affection as it has occurred in my experience: — No. 15. — M. G., f., set. 14, ad. July 18th. Ill six days; was out in a field, sitting in the sun, carrying children, suddenly became faint, and got pain in the head and vomiting, and has had vomiting ever since. She is always wanting to lie down, and complaining of her head. Skin cool. Pulse soft, open. Bowels very costive. Epigastrium not tender. With tannin and mineral acids the sickness quite ceased in a week, and she was much better. No. 16. — E. L., f., set. 24, ad. Oct. 25th. Ill since tbebeginning of August.

Remarks. — In both these cases the phenomena are a sudden cerebral "coup" followed by failure of functional power, and stomach disturbance. The second case is much the more severe, the prostration was very prolonged and considerable, and the tendency of the disorder to assume the character of malarious fever apparent. It seems plain that whatever amount of hyperaemia of the brain may have occurred, the history is by no means that of mere cerebral congestion, but rather reminds one of the results of concus- sion. If we bear in mind the primary exhausting action of heat, it will not be difficult to conceive how an excessive application of this agent may pro- duce such phenomena as above detailed. The occurrence of aguish disorder as the result of severe nervous prostration is highly significant as to the especial implication of the nervous system in malarious disease. The after symptoms, as Sir R. Martin well remarks, "are of extreme interest, and they, as well as the more chronic and subdued influence of insolation, throw much light on the pathology of the disease." The list which he gives appears to me remarkably to con- firm the opinion I have expressed that heat-apoplexy essentially consists in a functional paralysis of one or more great nervous cen- tres. It runs as follows : " (1) Severe mental depression with sense of weariness along the spine. (2) Impression of the sun being always shining on the person with tinnitus aurium. (3) Distressing formica- tion sometimes accompanied by a peculiar and general eruption and desquamation of the skin. (4) Deafness more or less severe with impaired vision, and inability to use the eyes in reading and writing. (5) Various paralytic affections, more or less general, as hemiplegia, and local palsies, as of the eyelids, cheeks, or upper extremities, with and without loss of sensation. Heaving and difficult breathing. (6) Distressing hysterical states of the nervous system, with absence of self-control in laughing and crying — the paroxysms being followed by great prostration of nervous power. (7) Interruption to natural sleep with incapacity for any kind of business. (8) Impression of alarm on any sudden movement of the body, and upon the occurrence of sudden noises. (9) Sudden epileptiform seizures, without loss of consciousness, followed by great nervous prostration." The forego- ing have been observed in sufferers who have returned to England. In India, he proceeds, " we are familiar with the acute sequelae to sunstroke, as ardent fever with acute delirium, remittent and inter- mittent fevers complicated with dysenteries, hepatic inflammations and congestions." These statements merit the most careful con- sideration, not only from the light they throw on the nature of heat- apoplexy, but from that which they shed on the pathology of a mul- titude of nervous disorders. Any man of experience in the manifold disorders of jaded and exhausted nervous systems will recognize at once how close is the resemblance between the results of tropical heat, and those produced by the ordinary causes in operation among CEREBRAL PARESIS. 83 the struggling multitudes of our large towns. It may be observed, (I.) That the most abiding results of heat-apoplexy are almost all referable to impaired functional energy of the cerebro-spinal system. (II.) That this impairment shows itself either in motor paralysis (5), sensory paralysis (4 and 5), either of common or special sensation, hyper- and dysagsthesia of the nerves of common and special sense (2 and 3), in debility and undue excitability of the emotional centres (6, 8, 9), and in similar states of the cerebral hemispheres and spinal cord (1, 7). (HI.) The earlier sequelae appear as the well-known consequences of vasomotor nerve paralysis. The picture which Sir R. Martin gives of the manifold and varying sequelae of sunstroke is altogether unlike that presented by actual organic disease. It is unlike in its causation, its non-progressive character, the inconstancy of the phenomena, and in the " juvantia." The occurrence of eruption in connection with, and apparently as the result of cutaneous dysesthesia is of much interest, and probably may be explained as the result of vaso-motor nerves becoming impli- cated in the morbid action. It will be remembered that one of the results of division of the sympathetic in some animals is cutaneous eruption. Romberg describes in the same way the development of prurigo from pruritus, a lichenoid eruption from a mere nerve affec- tion. The action of summer heat in promoting the occurrence of lichen urticatus is familiar to many of us. The effects of heat-apo- plexy illustrate very forcibly the development of morbid excitability and hyperesthesia simultaneously with impairment of motor power. It is difficult to say how far malarious poison is concerned in pro- ducing the phenomena we have been considering, probably it acts chiefly as a predisposing cause. The parallel, however, between these two morbid agencies is extremely close, and it is curious and instructive to observe that their results are sometimes identical. The cause of this correspondence no doubt lies in the fact that both act principally on and through the. nervous system, and that in the way of paralyzing its power. Admitting cholera poison to be a form of malaria, of which I think there is some notable evidence, we find in some recorded epidemics as sudden a death-stroke as can be occa- sioned by heat ; malaria will produce various forms of paralysis and epileptoid attacks, cutaneous eruption, and mental depression, besides the well-known fevers. This however may be said that malaria affects more specially the vaso-motor system, and heat the cerebro-spinal. As an imponderable influence, obscurely though unquestionably related to heat and malaria, we may notice electricity in its morbid action on the nervous centres. Dr. Radcliffe states in his lectures^ that a continuous electrical current of low tension seems to have the power of producing temporary paralysis of a nerve or nervous cen- tre which is traversed by it. Eckhard has shown that if the nerve of a frog's leg prepared for the purpose be included in a galvanic ' "Lancet," Feb. 28th, 1863. 84 CEREBRAL PARESIS. current it is impossible to produce contractions in the muscle by acting upon that part of the nerve which lie^ between the poles. In other words the part of the nerve along which the continuous galvanic current is passing, is paralyzed by the action of the current.' It is also a fact that the spinal cord may be paralyzed by the same means. If for example the spinal cord of a rabbit be included in the circuit of a voltaic battery the part between the poles may be cut, pricked, torn or even electrified without giving rise either to pain or convul- sion. Although the above-mentioned effects are expressly ascribed to low-tension electricity it seems indubitable that a shock of high- tension electricity produces very similar, and even more abiding. Numerous instances are on record in which individuals having been struck by lightning have suffered temporary paralysis of motion, and' special or common sensation, from which they recovered either spontaneously, or with the aid of tonic remedies. In these cases there can be I think little question that the nervous tissue is directly paralyzed from some molecular change taking place in its cells or fibres. I once experienced myself a severe shock from a very large Leyden jar, and well remember the overpowering general prostration I experienced, although the shock only passed through my forearm. It is impossible, I think, to conceive that any arterial spasm can explain the effects produced in this and similar instances. Certainly in the case of the frog's nerve dissected out, and remaining attached to the muscle above mentioned, there can be no question of local anaemia as the cause of the paresis. The " juvantia" also, as in Dr. Watson's case,^ where steel and tonic treatment effected a speedy cure of paraplegia in a girl who had been struck by lightning, deci- dedly indicate that the paresis from this cause is one of simple func- tional debility. Venereal excess is a powerful cause of cerebral paresis, as well as of spinal, few exceed it. Good Hufeland says, " it is proved beyond all doubt that nothing renders the mind so incapable of noble and exalted sensations, destroys so much all its firmness and powers, and relaxes the whole being as this dissipation." It is not too much to affirm that a state bordering on dementia has often been produced by sexual excess, and perhaps still more frequently by solitary vice. Esquirol says that immoral habits and the use of mercury are very frequently productive of that deplorable species of paralysis which becomes complicated with dementia and monomania.^ It is somewhat remarkable that sexual excitement should have so pernicious an effect, for the nerves of the genital organs are by no means large, their ori- gin is remote from the brain, and the loss of excreted matter can ' On one occasion I went to sleep with the negative pole of a 40 links Pulvermacher's chain in my hand, the positive being applied to my back. In the course of the night I found my hand was quite numb, but after removing the chain the numbness soou went off. 2 "Lectures," vol. i. p. 332. 3 V. Ritchie on same subject, "Lancet," Feb., March, 1861. CEREBRAL PARESIS. 85 hardly be regarded as anj serious drain on the system. The only way that I can see of accounting for the remarkable collapse which attends on any abuse of the generative faculty is, that owing to the intimate commissural connections between the lumbar enlargement of the cord, where the pudic nerves are implanted, and the superior and nobler nervous centres, the intense excitation of even a small and remote centre is communicated to the others, which as this sub- sides fall as much below as they have previously been stimulated above par. The depression is proportional to the previous excite- ment. Influenza is a common enough visitant among us, and familiar though its phenomena be, they seem to me of no little interest. That a person should be prostrated, as occasionally happens, almost instantaneously, and remain for some days in profound debility is surely very remarkable. Without speculating on the nature of the cause, let us simply consider how it seems to act. There can be I think no question that the nervous system is the one on which the stroke especially falls, and as little that the encephalic centres are prominently affected. The debility is by no means mere muscular weakness; it is described by Dr. Shapter as " an overwhelming feel- ing of lassitude and prostration of strength, with in many cases a loss of all muscular power, together with great anxiety of the pre- cordia, and agonizing fears of death." The expression of the coun- tenance is abattu. There are pains in every part, sensations as of being sore, beat, and bruised all over. Pain in the temples some- times prevents rest for several nights. Many observers have noticed the occurrence of neuralgia of the face. Apoplectic and convulsive attacks have occurred in some instances, in some also delirium, in others coma. These citations of the experience of others,' coincid- ing as they do very much with my own, may be considered sufficient proof that the cerebro-spinal centres are chiefly affected by the miasma, and that in a paralyzing way.' The catarrhal symptoms are for the most part such as indicate vaso-motor nerve paralysis, and atony of the capillary walls rather than actual tissue irritation. They, as Dr. Watson states, are not so essentially a part of the dis- order as the peculiar prostration, since they are occasionally absent. It must appear to every reflecting mind as a very important and thought-exciting circumstance that there should exist such a subtle, undetectable poison, or agency, as this of influenza. Standing as it does quite separate from the exanthemata, it links itself on the one hand closely with some of our commonest disorders, and on the other hand manifests no obscure affinity with pestilences, and with that most widespread of all maladies, malarious fever. ^ The intensity of its operation on the nervous system, and the fact that it is now 1 V.

Greenhow, testify to the origin of re- and intermittent fevers from influenzal aflfection. 86 CEREBRAL PARESIS. as it were domiciled* among us, makes it important to take count of it in dealing with a variety of obscure nervous disorders. It is prob- able that the more we come to know of disease the more we shall find that there exist a few great distinct morbific causes, which by acting on diff"erent parts, in different combinations and degrees and with slight modifications give rise to ever-varying forms of morbid action. The treatment of cerebral paresis must essentially consist in the avoidance or removal of all exciting causes, as well as in the employ- ment of all means that can recreate and invigorate nerve-power. The possibility of the paresis being dependent on remote irritation should be borne in mind. If, however, as is oftenest the case, it is primary and direct, we must endeavour to act on the enfeebled cen- tre itself. Among the means at our command pure and bracing air, generous diet, and healthful mental excitement are perhaps the most powerful. The influence of the latter is often marvellous ; it is really curious for any one to observe himself, and note how much more exertion he is capable of when his mind is thoroughly occupied and interested, than when the occupation is distasteful. I always ask my patients who complain of failing power (not of course depen- dent on organic disease) what recreation they like, and tliat I send them to, as the best for them. Under the head of food I may allude to the popular combination of rum and milk as being one of the very best restoratives that can possibly be given. A daily morning dose of it to weakly subjects is of great value, and in cases of an acute kind it may form almost the staple of the nourishment. As to medicines, our ordinary stimulants and tonics must be employed, the drug and the dose being matters for consideration in each individual case. I shall only mention particularly one or two remedies. Strychnia I have come to regard as a truly valuable cerebral toner, its action on the encephalic being not far inferior to that which it exerts on the spinal centres. It is a perfectly safe remedy with due care, and although I have employed it for years very largely I have never seen more than slight inconvenience produced by it, when it disagreed with some patients of unusual susceptibility. It should always be given in solution, and combines very well with quinine and iron. Phosphoretted oil I have used occasionally, but it is apt to cause considerable gastric disorder, and I have had but little encourage- ment to persevere with it. Dr. Radcliffe has recently spoken highly of the hypophosphites as remedies for states of nervous depression. My own experience of them in phthisis would not lead me to expect much benefit from them. Cod-liver oil is, I think, a remedy of real value, whether it act according to the chemical view of ministering to the nutrition of the nervous tissue, or not.

CEREBRAL PARESIS. 87 No. 17.— Mrs. P., fet. 48, broad and fat, seen July 24th, 1862. Has alwa3'S been a weakly-nerved person ; has had ten children. For six or seven years has suffered with bleeding piles. Her first attack of head symptoms was in October, 1861, the second in April, 1862. She did not lose consciousness in either, but had pain at the top of head and backs of eyes. She recovered from the first attack in six weeks ; from the second she still suffers. Complains of burning heat at top of head, at times has pain and great heat of head, the pain is increased by the recumbent position. Feels some numbness in both hands along the back of the fingers. Has double vision from paralysis of the right external rectus muscle. Head not tender. Pulse of good force. Does not feel weak. With strychnia and citrate of iron and quinine the external rectus regained its power, and I lost sight of her after October 23d till March 17th, 1863, when she returned to me feel- ing very weak, languid, and incapable of exertion. A week later the paralysis of the external rectus was complete. Much hemorrhage had been going on from the piles. She had great pain at the right posterior part of head, increased on lying down. The double vision caused her much annoy- ance from the objects passing her in the streets confusing her. Her piles were now got rid of by operation, but the hemorrhage from the bowel continued whenever she had a motion, and the state of the right eye was unchanged. Nothing could be detected in the rectum to account for the bleeding except a loose and baggy state of the mucous membrane. This was at last arrested by tannin taken internally, aided very materially by removal to the country, where her general health and strength much im- proved. By the middle of June she had regained a good deal of power over the external rectus. I urged a return to the country, but this was not carried out; however, the improvement continued, so that November 10th, when I last saw her, she had almost perfect power over the formerly paralyzed muscle. Some bleeding had recurred, but not to any great extent. Remarks. — This case is an interesting example of a limited paresis of the nervous centres, involving the origin of one small nerve only. That the paralysis did not depend on organic disease must I think be admitted from the beneficial effect of strychnia, iron, and quinine on the first, and of country air on the second occasion. There can be little doubt that the long-continued hemorrhage was the cause of the general debility and local paresis, but it is remarkable that the latter existed before the former was felt to any notable extent. The pain in the head was probably neuralgic, yet it was aggravated on lying down. Enemata of krameria infusion, lead and opium pills, and sulphur internally failed to arrest the bleeding after the piles had been removed. The case is instructive in various respects, as showing (1) the connection between debility and paresis; (2) the necessity for close inquiry into the possible causes of paresis; (3) the superiority in some instances of a pure air to tonic medicines; (4) the dependence of hemorrhage in some cases on atony of vessels. 88 SPINAL PARESIS. CHAPTER VIII. SPINAL PARESIS. The nature of this state in general, and its efficient causes have been sufficiently described in the previous chapter; it only remains to illustrate its phenomena when it affects a different locality. This I shall endeavour to do by the relation of some cases, which appear to me of considerable interest. No. 18. — C. M., set. 39, butler, ad. Aug. 17th, having been ill five weeks. He states that his illness came on gradually, apparently from excess in drink- ing, not in venery. He is paralyzed to a considerable estent in both hands, so that he cannot dress himself, nor pick up anything. His feet are also weak and flap down in walking. There is a great if not complete loss of sensibility in the paralyzed limbs. The paralysis is getting worse. He feels very weak all over. Head hottish, but there is not much pain in it; he has never lost consciousness. Tongue coated at back. Bowels costive. Pulse large, soft Urine of sp. gr. 1014, of good full colour, not albuminous.

He improved gradually and was nearly quite re- covered by December 20th. I have seen him lately, and find he has had no return of the paralysis during the six years and a half that have elapsed since he was under my care In some cases it appears as if alcoholic stimuli taken in excess acted on the spinal centres much in the same way as they do on the cerebral, impairing and depressing their functional power. Last year I attended a female, who had been extremely addicted to brandy-drink- ing for years ; as far as I heard her history she had never had delirium tremens, but she lost both motor and sensory power to a great extent in both upper and lower limbs for some months before her death. In her it is possible that the alcohol had caused sclerosis of the cord, as no remedies were of any avail. No. 19 — N. D., aet. 20, m., ad. September 10th, 1858.

Can now walk and feed himself; he cannot bear so strong a current as before. The same treatment was continued till the end of November, when he was discharged with only a slight degree of weakness remaining in the legs, which was referred to the knees. It seemed that the extensor muscles of the thighs had not regained their full power; he was able however to walk very well, and his arms had become quite strong. The dose of strychnia was gradually increased to gr. ^ ter die. A curious circumstance observed by himself was that his feet swelled during the night, so that he could not get his boots on in the morning, but after walking about the ward a little the swelling subsided. His urine was free from albumen and was otherwise healthy, except that at one time during the catarrhal affection it deposited much uric acid. I cannot but regard this as a very proving case. A man is admitted ■with incomplete paralysis consecutive (as he reports) to catarrh, after improvement has commenced he relapses, and becomes considerably more paralytic than at first, while simultaneously he is affected with asthenic bronchial and gastro-intestinal catarrh. Under a persistent tonic treatment he makes a good recovery. It seems impossible not to recognize in such a case as this the operation of a depressing mi- asm (influenza), acting with unusual potency on the "whole nervous system. There is no indication of the paralysis being other than primary and direct, or that it is in any way attributable to remote irritation. The phenomena of vaso-motor paralysis were well marked in the skin and the mucous membranes, and the nocturnal swelling of the feet v^sls owing, I believe, to the same condition. . Is it con- ceivable that the vessels of the nervous centres were in a state of spasm, and that the paralysis depended on anaemia ? What would have been the result of treating this case in the same way as the one recorded by Ollivier, v. p. 73 ? No. 20. — A. W., female, set. 9, has had paraplegia last three months, it increased rapidly after it commenced, and in fourteen days was as bad as 90 SPINAL PARESIS. it is now. She cannot stand or walk, but can move her legs as she sits. There is no loss of sensation in the lower limbs, they have wasted consid- erably. The muscles of the lower limbs are very insensitive to the interrupted current, more particularly the extensors. The spine is much curved, convex backwards and to the right side. When the legs first became weak she had more constant pain in back, but it did not seem to be increased by friction. Beginning from the two lower dorsal vertebrae there is tenderness on press- ing the spinous processes all the way down to the sacrum. No sign of any tumour in front of abdomen or thighs, no trace of any abscess. At times she has constrictive sensations in the abdomen.

She cannot stand, but wriggles her- self about pretty actively on her knees. The back appears much straighter than it used to be, she can at any rate sit quite upright without showing any deformity. There is still local tenderness in the lumbar spines as tested by pressure, or applying a hot sponge.

Sound sleep sometimes follows, but is by no means a necessary result of its beneficial action. The dose is ^y every quarter of an hour till some manifest effect is produced. If there is any difiiculty in administering it by the mouth, the method of subcutaneous injection may be employed. In the latter case the ^iv of acid are to be combined with "\,xxx of water. M'Leod has no doubt from his experience that it has the power of promptly staying cases running on to chronic insanity on the one hand, or exhaustion and death on the other. As its best ascertained therapeutic effects consist in removing various neuralgic affections, it is probable that it is more appropriate to states of the brain in which simple excitement of the tissue constitutes the disorder, than to those of which hyperasmia forms an essential element. It is a less depressing remedy than the two preceding, but an over-dose produces a stuporous condition and other phenomena resembling, those attending an epilepsy. The foregoing remarks relate to the treatment of sthenic delirium, but we have seen that acute or active delirium may be asthenic. It may be no easy matter to distinguish between cases requiring de- pressant measures, and those for which stimulating are essential. If we read Grave's remarks on the subject of giving wine and opium in fever we cannot but remark that he felt it not uncommonly to be a difficult question to decide when they were to be given, and when withheld. He states, " that we must rely in the more advanced stages of fever on the tact acquired by previous experience and re- flection, and must often depend more upon a correct estimate of the general state of the patient than upon the appearance or absence of any particular symptom.'" Sleeplessness with restlessness and irri- tability, the patient constantly endeavouring to leave his bed and having delusions — these symptoms may urgently demand wine and opium. Violent and continuous delirium forbids, in Graves's opinion, a stimulating treatment, but this does not hold if though there be a good deal of raving it is nocturnal. Stokes gives a case (p. 404)^ where there was violent delirium throughout the night (two days later it is simply reported that there was such delirium without specifying that is was nocturnal), in which 16 ounces of wine daily with camphor, musk, and opium appeared to be highly beneficial. In one of Dr. Todd's cases of erysipelas^ the patient had such violent delirium and created so much disturbance that he was obliged to be placed in a separate ward. With |ss of brandy every two hours and ^,xx of laudanum every four hours the delirium was unabated, but diminished considerably and soon ceased after the brandy had been given every hour, and the laudanum had been replaced by bark, chloric ether and ammonia. In another case, one of epileptic 1 " Clinical Med.," p. 187. 2 "Dis. of the Heart and Aorta." 8 "Clin. Lect. on Acute Diseases." 108 CEREBRAL EXCITEMENT. delirium, very violent and constant delirium subsided in about four days under gss of brandy every hour, with carbonate of ammonia and laudanum every four hours. The pulse steadily declined in fre- quency during the administration of the stimuli. Todd speaks very confidently also of the efficacy of alcohol in preventing delirium in patients suffering under various acute diseases. He evidently holds that it is better to err on the side of giving too much than too little stimulus. The points to \¥hich we should have most regard in en- deavouring to determine the quality of the delirium we have to deal with are : (1) The general condition and constitution of the patient ; (2) The state of the urinary secretion; (3) The state of the pulse; (4) The quality of the first sound and impulse of the heart ; (5) The state of the pupil ; (6) The state of the skin ; (7) That of the bowels. If the patient be enfeebled from any cause, and has not previous to his illness enjoyed vigorous health ; if his urine is in good quantity, not highly acid, red, or of high spec. grav. ; if the pulse is easily compressed ; if the first sound of the heart and its impulse are weak ; if the pupil is dilated ; the skin not very hot and dry, and the bowels relaxed, we have good grounds for expecting that stimulants will be beneficial. In proportion as the above signs are less marked, the indications become less clear, and we must resort to what is often a wise proceeding, viz., testing the condition of the system with some remedies, the result of which may lead us to take the right course. The more we can perceive the signs of excitement without power in the cerebral disturbance, the more bold we may be in our adminis- tration of stimulants and support. In cases of this kind opium is often necessary, and its dose must depend on the degree of excite- ment, and on various other circumstances. Too small doses may only aggravate the excitement, and too large may bring on dangerous or fatal stupor. The determination of this point is one of the most delicate in therapeutics, and cannot be solved, at least in all instan- ces, by administering small tentative doses in succession. I am much inclined myself to give large doses of hyoscyamus, as 9j of the extract, in cases where it might not be safe to give a full dose of opium. If we prefer the latter the amount of cerebral excitement is the chief measure we have of the quantity of the drug which will be requisite to calm it. If the pupil be contracted, belladonna may be given as an hypnotic with advantage as Dr. Murchison tells us. Hyoscyamus would probably be suitable in the same state. In cases of the kind we are now considering brandy mixed with milk will be found one of the best forms for administering stimulus and food. It should be given of course at very short intervals, say 5ij of brandy -f oSS or 5vj of milk every hour or half-hour. No. 27. — W. L., set. 25, of spare frame, delicate constitution, carpenter, seen March 28fch. Ill with acute rheumatism about ten or twelve days, his head began to be affected two days ago. Five years ago he was under Mr. Culpepper's care for a very severe attack of acute rheumatism; attended CEREBRAL EXCITEMENT. 109 with endocarditis and pericarditis. Five years before that he was under my care with similar disease. On March 21st he had ten leeches to the precordia for threatening cardiac inflammation, poultices were subsequently applied, and calomel and Dover's powder given every three hours with a draught of pot. nitras, potas. bicarb, and sod. phosp. 25th. Is nearly free from the pains and swelling of the limbs except in the extensors of both feet; skin still exudes an oifensive copious perspiration. 26th. Gums affected. Rheu- matism has quite disappeared, just as it did five years ago suddenly while the pericardium became inflamed. Calomel omitted, Dover's powders and salines continued. 27th. In the course of the night he became quite de- lirious and incoherent, uttering alarming shrieks so as to disturb the neigh- bours, with fits of fearfulness and apprehension that the ceiling was about to fall, &c. Eyes wild and restless, can scarcely be made to comprehend any question. Head hot and skin generally. Tongue dry and covered with yellow crust. No urine passed since last evening. Hands are tremulous as in delirium tremens. Hair cut short and cold applied to head, hot mustard fomentations to the feet. Opii gr. i 3tiis horis with effervescing draughts. Furious delirium continued all the day; four persons were required to keep him in bed, he would not take the pills or mixture. At 5 P. M. Mr. Cul- pepper gave him gr. j of opium, and at 9 P. M. gr. ij, matters were then greatly worse. At 11 P. M. Mr. C. was sent for, the patient was said to be in a strong fit of convulsions. When he saw him, he was in a terribly excited state, eyes staring, jaws clenched^ heart beating violently. Pulse 130. Great heat of surface. Tr. digitalis 5ij + tr. opii 5j W'lS directed to be given in two doses, at 12 and 3 A.M. At 6 A. M. he had liq. opii sed. 5j in two doses. I saw him with Mr. Culpepper at 9.30 A. M., and learned the above history and that he had had no sleep for two nights. Pulse 117, of good force. Tongue denuded, cracked, red, covered with sordes. Is partially conscious, does what he is told, says he has no pain anywhere, is constantly talking deliriously. Rheumatism has quite disap- peared in spite of counter-irritation to the limbs. Urine passed in bed. Head rather hot. Heart's sounds fairly clear, no pericardial effusion, slight questionable exocardial bruit. Right pupil dilated until lately, is now of medium size and fixed. Left eye lost. No pneumonia or bronchitis. We agreed that he should have six leeches to the temples, cold to his head, and gp. I of tartar emetic every half hour. 31st. He began the treatment at 11 A. M. of 28th, and took gr. ^ every half-hour till 11 P. M., when the pulse was 95, the skin was cool, and the delirium nearly abated, in short everything going on well, which induced Mr. C. to give the mixture less frequently, every one or two hours. At 5 A. M. of 29th he was not so well, so the mixture was given as before with liq. opii sed. n^iv in each dose, and from that time to 10 P. M. of 30th he has made rapid and permanent improvement, and is now quite himself again in every respect, asking for and taking food, and knowing every body about him ; delirium quite ceased. In fact but for the return of the pain and swelling of the right hand one could not say what had been the matter. The left shoulder is also painful. Complexion clear, countenance calm, pulse 86, and respiration tranquil. April 1st. Sleeps and eats well; omit the antimony and opium. 2d. A light tonic with sodse phosph. was given, as the urine still deposited lithates. Joints free from rheumatism. 6th. Is up and dressed and considers him- self quite well. Mr. Culpepper, to whose kindness I am indebted for the report of the case, adds that during the four days he took over 30 grains of 110 CEREBRAL EXCITEMENT. tartar emetic and 5ij of" lio(- opii sedat. Rheumatic pains reappeared on night of 29th and continued till April 3d ; all other symptoms gradually but most distinctly abated, and not the slightest bad effect was produced by the antimony, no approach even to nausea or sickness, or purging, or depression of the heart's action. After the 30th the medicine was given less fre- quently. Remarks. — There can be no question that the tartar emetic was really the eflScient means of this patient's recovery. Opium had been taken pre- viously without benefit, and was not given the first day, when nevertheless a considerable sedative efi"ect was produced. The relapse which ensued when the antimonial was given less frequently, and the steady improvement after it was resumed at the former rate, prove that it was the chief remedial agent. Its action seems to have been remarkably limited to the brain calming the excitement of its tissue without producing any other notable effect. The case was evidently not one of ordinary rheumatic fever delirium; there seems to have been actual metastasis of the morbid action from the joints to the brain, with subsequent recurrence of it in its usual site. Considering that the heart had been severely attacked before I think it - is very doubtful whether there was any actual affection of it on this occasion. If there was it was slight, and had I believe no connection whatever with the cerebral symptoms. Altogether the case may stand for a Uapabeiyixa of sthenic delirium. The following case related by Dr. Posner^ is worth comparing with the foregoing : — No. 28. — A man, set. 37, fell ill of acute rheumatism. Both hands were affected, the pulse was 100, and the other symptoms were as usual except that he was remarkably restless. The inflamed parts were much relieved by leeching, but the elbow-joints became engaged, and the upper arm and neck muscles were painful. On the next day after considerable delirium the joints became quite painless, the pulse was 65, the patient only com- plained of occipital pain. There was no indication of intercurrent delirium tremens, the cerebral disorder was viewed as a rheumatic meningitis, and treated by local detraction of blood, and ice applications, with tartar emetic opium internally, and mustard poultices to the joints which had been in- flamed. The delirium continued two days and nights in spite of repeated bloodletting, the pulse fell more and more, and the joints remained painless until large doses of opium were administered, which produced on the third night sleep for seventeen hours, out of which the patient awoke rational but with severe pains in the neck and stiffness of the elbow-joints. The pulse had risen moderately and the general condition was better. After a second tranquil night the pain returned in the joints which had become affected with all its former severity, and this condition lasted some days, when it suddenly ceased, and in its place the old cerebral symptoms returned. These yielded again to the opiate treatment, and the joints became affected for the third time, and remained so until the disorder disappeared entirely in about fourteen days. The heart was never attacked. No. 29. — Mr. L., set. 25, a delicate man, seen in consultation with Mr. Gr. Brown, Dec. 13th. He had been ill about ten days suffering with 1 " Med. Ceatr.

The milk and lochia have continued : she has had no unfavourable uterine or other symptoms, no indication of fever. She has been quite sleepless and maniacal, raving and talking continually ever since her confinement in spite of large doses of opium, as much as 5ss of liq. opii sed. in one day, and some large doses of henbane. They have quieted her a little, but not much. She answers quite rationally when spoken to by me, but as soon as she is left talks deliri- ously. Urine normal. Bowels have been confined, are open now, and she has been better since. Pulse of tolerable strength, 88.

Mr. F. then administered tr. hyoscy. 5ijj ^tiis horis, with which she became quieter ; had a good night Feb. 2d, and improved materially. The antimony caused vomiting after four doses and flushing of the face. She went on taking tr. hyoscy. About 5^ daily for some days and quite recovered. Remarks. — In this last case the treatment which succeeded so well in the first was evidently inappropriate. Yet from the appearance and con- dition of the patient I had great hopes that it would prove successful. Per- haps it may not have been altogether useless, by rendering the brain more amenable to the influence of the henbane than it had been previously. In this respect the utility of what are called lowering remedies is I think some- times overlooked. They may not apparently eS"ect much themselves, but they prepare the way. for others. The conclusions to be drawn from the above cases seem to be these. (1) That the quality of the vis nervosa in delirious disorder varies greatly, (2) That it may be very difficult to ap- 112 CEREBRAL EXCITEMENT. predate or gauge this quality correctly. (3) That nevertheless it is most important to do so, as the treatment depends upon it. (4) That any exclu- sive mode of treatment by stimulation, or the reverse, or by sedatives is out of the question. CHAPTER X. DELIRIUM TREMENS. We next come to the state known as delirium tremens. This is for the most part considered to be invariably the result of alcoholic excess, but I think there can be little doubt that a state closely resembling it, if not identical, may be generated by other causes. Watson states that this may happen from prolonged anxiety, J. Johnson from over-study. In continued fever a state closely resem- bling delirium tremens is not unfrequent. The case is narrated^ of a stoker of good character serving on board H. M. S. Reynard, who fell apparently in consequence of excitement at the murder of two of his shipmates by the Japanese into a state of perfect delirium tremens, not one symptom being absent. It was proved that he had not been indulging in alcoholic excess. He was put to sleep with tr. opii ^ 40 + chlorof. ^ xv. Fox records^ a case to the same eifect, the disorder supervening on exposure to cold and wet. He is positive that no indulgence in intoxicating liquors had anything to do with its production. Dr. Monckton^ relates the case of a female, set. 28, who rather more than three months after her con- finement presented an almost typical state of traumatic delirium tremens; "the breast abscess consummating the overthrow of brain equilibrium," for which previous and successive mental shocks had prepared the way. This testimony as to the production of delirium tremens by other causes than alcoholic seems to me very important, as proving that the peculiar morbid state is not necessarily one of poisoning at all. It may be a sequela, or result of poisoning matter, ■which has passed away from the system, or may be solely a diathesis. The discussion which has lately arisen respecting the proper treat- ment of delirium tremens makes a careful reconsideration of its pathology necessary. Those who contend that the disease is specific and dependent upon alcoholic poisoning deny that it ever originates from deprivation of the customary stimulus, and assert that in all instances where this is apparently the case the paroxysm has only been accelerated in its arrival by the accident or disorder, which has interfered with the usual indulgence. Dr. Marston however I "Lancet," Oct. 11th, 1882. 2 « Laucet," May 7th, 1859. s "Edin. Med. J.," Oct. 1860. DELIRIUM TREMENS. 113 adduces evidence^ which very materially corroborates the older view, and taken together with other experience renders the above- mentioned hypothesis very questionable. He shows that delirium tremens does come on in soldiers commonly from the first to the seventh day after the privation of liquor, and this in men who had not suffered from it before. He argues, I think, convincingly and conformably to the analogy of other similar agents, that the nervous' system becomes habituated to the constant use of alcoholic stimulus, so that, although more or less injured by it, it feels seriously the deprivation. Probably most of us have some familiar experience of a similar kind. Thus men who have been accustomed to take wine or beer moderately have tried to leave them off for some reason or other, but found their efficiency for work so much impaired thereby, that they were obliged to resume their usual allowance. This is on a minor scale much the same thing as occurs in some cases of delirium tremens. On the other hand, it seems to me that if this disease was invariably the direct result of alcoholic poisoning, the good effects of abstinence ought to show themselves very speedily and decidedly, so as to put the matter out of all question. Dr. Laycock, who has taken a principal part in advocating the abandonment of the former routine treatment by opium, considers delirium tremens as "a vague term." He thinks that various cere- bral affections of melancholic character are grouped under this head, that our diagnosis is imperfect, the etiology obscure, and the patho- logical anatomy altogether erroneous. He does not appear to dis- tinguish, certainly not pointedly, the acute disease termed by some D. ebrietatis from the more chronic affection attended with depres- sion. Yet this seems to be a main point. Dr. Blake regarded them as opposite and distinct diseases, the one being the immediate conse- quence of intemperance, the other arising from the sudden cessation of accustomed intemperate stimulation ; the one requiring the cau- tious use of depletion, the other the administration of stimuli ; the one belonging to the phlegmasiis, the other to the neuroses. Cop- land makes a similar division of the disease into species; "the one being evidently connected with inflammatory irritation of the arach- noid and associated with great irritability ; the other consisting chiefly of this last state attended by exhausted nervous energy." He adds, however, immediately, and this seems very important, "yet it often presents intermediate forms or modifications, which cannot be referred to the one species more than the other." He insists that the treat- ment should be modified according as it approaches to the one type or to the other. Dr. Marston in his excellent paper (loc. cit.) makes the same distinction, and further groups in a separate class cases which are complicated with visceral disease, renal, hepatic, gastro- enteric, central. The first form, he says, evidently implies acute alcoholic poisoning, while the second is a delirium of drunkards in ' "Brit. Med. J.," Dec. 19th, 1863, 114 DELIRIUM TREMENS. contradistinction to a delirium from drink. The subjects of the first class are soon right after an emetic purge, and two or three days' quiet. Those of the second after free purgation will probably require opium and stimulants. Graves, though not separating his cases so widely from the etiological point of view, lays down most positively the necessity for very different treatment in diflFerent cases. In the young and robust, the disease may demand strictly antiphlogistic measures, including venesection, leeching, and cold to the head ; while in the old debilitated and confirmed drunkard, "we are often obliged to exhibit opium from the very commence- ment, and that in large doses combined with stimulants." Between these extremes, he proceeds, there are many intermediate varieties, each requiring a special modification of practice. Tartar emetic boldly exhibited is often our sheet-anchor in delirium tremens, espe- cially when there is evidently active determination to the head. In some cases it may be given alone, in others combined with opium. Mr. Solly, we suppose, states only the general experience of surgeons as to the liability of habitually excessive drinkers to suffer from delirium tremens, when after the shock of an injury they are re- strained from their usual indulgence. Mr. Erichsen' only differs in recognizing two distinct types of traumatic delirium, " the one inflam- matory, the other irritative," the treatment of the first being strictly antiphlogistic, that of the other requiring full doses of opium, con- tinued until either sleep is induced, or the pupil contracted : — while if there be also much depression, stimulants are requisite. . He dis- tinctly admits that this disorder may befall persons who are not intemperate, but who have an irritable nervous system. Dr. Peddie^ considers that the state of the brain in delirium tremens is one of alcoholic erethism, the alcohol occasioning those relative changes in the sanguiferous system of the encephalon, the tendency of which is to pass from irritation, from abnormal activity of circulation and function, to inflammatory action, according to the severity of the attack, and other circumstances. He treated eighty cases with uni- form success by tartar emetic in doses of gr. i-| in simple solution every two hours, or at shorter intervals, according to the degree of excitement and irritability. The action of the antimony appears to be chiefly sedative. Its direct influence is to reduce the vascular excitement of the brain, soothe the nervous system, and diminish muscular power, and its more indirect action is exerted on the func- tions of the skin, kidneys, and intestinal canal. The advocates of the more recent view hold that delirium tremens is a specific toxae- mia from alcoholic excess, and does not consist merely in the nervous irritation and exhaustion consequent on the withdrawal of a favourite stimulus. They insist that many persons cease from alcoholic excess, and become sober without suffering in any degree from this disorder. The records of prisons are appealed to to es- " Science and Art of Surgery," p. 90. 2 ugjin, iyiecl. J.," June, 1854. DELIRIUM TREMENS. 115 tablish this point. The occurrence of traumatic delirium in drinkers is explained by supposing the injury to induce the earlier occurrence of a paroxysm which would have ensued without it, just as an attack of influenza or some other casual disorder might have done. If a mere expectant treatment be followed, according to Dr. Ware, of Boston, a paroxysm of delirium tremens terminates by natural sleep in from sixty to seventy-two hours, dating from the time when the state of entire watchfulness and delirium commences. The mortality on this plan is stated to be extremely small, only one death having occurred in twenty-nine, and this case being complicated with acute disease ; while out of fifteen cases treated with opium in small or large doses six died, two of these being complicated. On the other hand in the Edinburgh Infirmary, where for many years the dis- ease seems to have been treated with laudanum and whiskey in a very careless manner, the mortality is stated to have been 35 per cent.; and in St. George's Hospital 14.6 per cent.; in the infantry regiments 17.6 per cent. ; and in the cavalry 13. 8 per cent. Dr. Gairdner's recent experience at Edinburgh is of one death among thirty cases treated in an extremely simple and natural manner, and that one being complicated with a very extensive double pneu- monia. Laycock himself has treated sixty-eight cases without opium or stimulants, and has had only two deaths. These statements certainly deserve grave consideration. The one which is of main importance is the assertion that the paroxysm of delirium tremens is self-limiting, ceasing as Dr. Ware affirms in from sixty to seventy- two hours. Dr. Laycock indeed extends this period considerably, to from four to fourteen days (his cases averaged six). This is cer- tainly a considerable discrepancy, the shortest period assigned by Dr. Laycock being a day longer than the longest given by Dr. Ware. It would indeed require a considerable faith in the spontaneous ten- dency of the disease to a favourable termination to allow a man to remain sleepless and raving day after day without making judicious efforts to procure sleep. Dr. Laycock indeed seems to think that sleeplessness is no such serious matter ; he says that he knew one gentleman who never slept a moment for a month yet with no bad results. Drs. Watson, Latham, and Grattan think very differently as regards the state of fever patients, which the former expressly compares with that of delirium tremens. They state that two or three nights spent in restless delirium are followed by the worst consequences, and that patients who pass three nights in succession in that way almost invariably die. Now though we admit that the delirium tremens patient may, at least in some cases, have more vital resistance than the fever-stricken one, yet it can by no means be granted that continuous sleepless delirium will not tend very materially to induce exhaustion, and death by asthenia. That a routine treatment by laudanum and whiskey is not advisable is most freely conceded ; we no more wonder at the high mortality under such a regime, than we do at that which results in pneumonia, when 116 DELIRIUM TREMENS. a numb.er of patients are taken indiscriminately, and all are treated by bleeding. Our belief is that our practice in delirium tremens, as in all other diseases, should be to a very great extent governed by the vital condition of the patient. If we had a case of continued fever where the symptoms were mild, and there was no remarkable excitement or depression, we should not interfere and require the patient to swallow a dose of wine or brandy every hour as we should do if there were indications of perilous depression. We hope we have learnt the truth of Schonlein's wise saying that it often happens to good physicians to find no indication for treatment, to bad ones never. On this view we quite understand that there may be many cases of delirium tremens in which a purely expectant treatment would be the best proceeding. This will specially be the case when the disorder supervenes upon a recent debauch ; and when all that is needed is to enable the patient quietly and safely to recover from its injurious effects. Dr. Laycock seems to have met with this state so often, twenty-one out of twenty-two patients alluded to by him in his first paper' being actually alcoholized when they were admit- ted into the hospital, that we cannot but think that his cases are mostly of the acute toxsemic character. The only one which he de- tails in his second^ paper was a case of prolonged debauch, in which, though sleep did come on in nine days without sedatives, we are by no means convinced that it might not have been advantageously induced much sooner. The points which seem to us fully established by the widest experience are the following. (I) That cases of de- lirium tremens differ often very widely from each other, and that their management must vary accordingly. (II) That this difference may depend, (a) on the original strength of the constitution ; {b) on the degree in which the nervous and other systems have become impaired by habitual excess, by anxiety, or other causes ; (c) on the tendency to sthenic inflammatory excitement of the brain ; {d) on the circumstance whether the disease succeed immediately to a drinking-bout, or supervene on a condition of chronic regular tippling, which has been accidentally interrupted. Before proceeding to illustrate the above points we would remark that it does not seem wise to set aside and ignore the experience of our predecessors because it does not agree with our own. We hold that all facts, faithfully observed and recorded, have an undying value, they may not accord with others which occur at different times and places, nay, they may seem to be contradictory, but if they be real facts, they must be taken into account in any attempt to construct a true theory of the disease. It is marvellous how prone the best of us are to one-sided views, how averse to look fairly at all sides of a question. We remark further that with regard to what Dr. Laycock calls the heroic treatment of delirium tremens, it is impossible to suppose that it is entirely negative. » "Edin. Med. J.," Oct. 1858. 2 Ibid., Mar. 1862. DELIRIUM TREMENS. 117 Either it must do good, or be injurious in the great majority of cases. He himself is not sparing in his anticipations of evil, con- cluding that " the continued or increased use of the causes will aggravate the effects, and change that which would otherwise be acute and transient into a chronic and permanent, if not a fatal dis- ease." It is also we think to be considered that we need in the practice of medicine not only to have general rules for the manage- ment of ordinary cases, but special directions for various exigencies. Dr. Laycock is scarcely consistent with himself in allowing the use of alcoholic stimulants (4 to 6 oz. of brandy daily in one case) where there is prostration, and in admitting that in one class of cases opium and its salts have the "most beneficial effect." This seems to me to concede nearly all that a judicious practitioner, who was not prepared to adopt expectancy, would contend for. Now, taking up our last point first, we think that all cases where the symptoms ensue immediately on casual alcoholic excess, should be distinctly separated from others where this is not the case. In this we agree with Dr. Blake, Mr. Solly, Dr. Copland, Dr. Marston, and Dr. Morehead. These cases may require very little treatment, perhaps only an emetic and a purgative. Dr. Morehead' gives calo- mel gr. viij -t- gr. j of morphia at bed-time after a hot foot bath and cold affusion to the head. In robust young men he finds cupping to the neck often useful. The nervous system in such cases being in a tolerably sound state rights itself before long as soon as the morbid influence has passed off. In other cases the attack super- venes on a debauch, but the patient is also more or less habituated to alcoholic excess previously, perhaps for many years. Here it depends very much on the condition to which the nervous system has been reduced by the previous intemperance what effect the debauch will have. If the nervous power be tolerably intact, the case will be nearly of the same kind as that first considered ; if the reverse is the case, it may be much more serious. Dr. Brinton gives a good example^ of a man who had been long addicted to hard drinking, and was admitted after ten days' nearly continuous debauch in a state of incessant struggling delirium, which continued for more than twenty hours. He was allowed 3 to 6 oz. of brandy daily, and vin. ipec. ^xv + tr. opii ^Lvij -j- spt. asth. chlor. n\^x was admin- istered every three or four hours. In twelve hours he slept, and was calm and rational the next day. When admitted he was in the third or fourth day of his third attack of delirium tremens. Now it is evident that the nervous system of this man could not have been very profoundly deranged in spite of all his excesses, if he could recover so rapidly under such simple means. But now, had this patient had a tendency to inflammatory excitement of the brain, such as Dr. Morehead describes as common among Europeans in • " Eesearches on Disease in India," vol. ii. p. 533. 2 "Lancet," June 16th, 1860. 118 DELIRIUM TREMENS. India, one may feel very confident that he would not have escaped so lightly. He would then have been in the condition which Mr. Solly describes as essentially one of hypersemia, and as more relieved by a general warm bath, and cold to the head, than by any form of opium. A case recorded by Dr. Peddie' illustrates this state well. A man, set. 41, on the sixth day of his third attack of delirium tre- mens was highly excited and delirious, attempting to get out of a window. He had had previously smaller and less frequent doses of antimony, but was now ordered gr. ^ every hour with beef-tea liber- ally. After each dose, he was observed to become calmer and more rational, slept soundly in the afternoon, and next day was quite con- valescent. This case would surely have been rendered much worse by opium and stimulants. It is on account of the prevalence of such conditions in India, that Dr. Morehead has recourse so fre- quently to tartar emetic and opium, giving gr. | of the former -f- TT\^xxx of tinct. opii 2dis horis, and employing, if need be, at the same time stimulants and cold affusion. The importance of the original strength of the patient's system is well illustrated by the following case which occurred in the practice of Dr. Hamilton Roe. A publican, habitually intemperate, a strong thick-set man, was walking about his shop in a state of considerable excitement, inco- herent and wild, flourishing a knife, and refusing to take any medi- cine. He was coaxed to take a pot of porter in which were dissolved 6 grains of tartar emetic. The result of this " quietner" was that in one hour he was subdued, so as to take willingly gr. iij of opium, which put him to sleep, and he awoke after six hours, perfectly well. " II va sans dire" that there are not many cases of delirium tremens which it would be advisable to treat in the same heroic way. But it is abundantly clear that the remedies were highly appropriate, and answered their purpose admirably. We cannot think that an expectant treatment involving prolonged delirium for many days, (Dr. Laycock gives a limit of fourteen) would have been preferable to the above sharp and short cure. Such a case, or that quoted from Dr. Peddie, may stand as a type of truly sthenic delirium tre- mens, in the management of which stimulants are of course unde- sirable. Dr. Fraser^ records two cases of delirium tremens in both of which the pulse was full and rather hard, and the symptoms had supervened on a recent debauch, the patients being robust working men. In the first, sleep came after ^xx of tr. physostigmatis had been administered, in the second where there was also limited pneu- monia after ii^xxvj. Both were quite convalescent in two days. Dr. F. limits the use of the remedy to sthenic cases, and weak pulse he regards as a contraindication. He believes the physostigma to act by depressing the action of the heart, and so lessening the supply of the blood to the brain, in consequence of which the disposition to wakefulness is. conquered. The following history probably de- i V. Loc. citat. 2 "Edin. Med, J.," Aug. 1863. DELIRIUM TREMENS. 119 scribes a condition in which the nervous power was less resisting, though its excitement was equal to that displayed in the first case. A strong male, of mid-age, habitually intemperate, had drunk hard up to the time of attack. He was seen by Dr. H. Roe about forty- eight hours after delirium had commenced, and had been treated previously with small doses of opium ineffectually. His pulse, when seen, was full and quick, skin rather hot, head hot, eyes and face red and flushed, delirium rather fierce. Three grains of opium were given at first, but had only the effect of causing further excitement. Two hours after, 6 grains were given, which quieted, but did not sleep him ; and three hours later he took 6 more, slept almost imme- diately, and woke after six or eight hours quite rational and re- covered. No stimulants were given. It seems to me that it would be quite unfair to object that in this case the opium was not the cause of the sleep which would have come on spontaneously with- out. Fifteen grains of opium in five hours is no placebo, and beyond all question had not the nervous system been in such a state of ere- thism as to tolerate, and in a measure resist it, the dose would have proved fatal. The administration of opium in such full doses re- quires a master's discrimination, and I am by no means inclined to advocate a frequent resort to such practice. That, however, in appropriate cases it produces excellent results, is, I think, undeniable. In many instances I am inclined to think large and repeated doses of extr. hyoscyam. afford a safer sedative. Trousseau's rule for the administration of opium is a good one; he says if the disease is 20, opium must be 21. The difiiculty is to measure the disease correctly ; we have no meter wherewith to gauge vital power. In strong con- trast to both the preceding cases we place the one recorded by Mr. Jones, of Jersey.' A male, £et. 48, seen Sept. 9th. Has had pre- viously fits of the horrors, and has been muddled for the last two months. Has had no sleep now for four days and nights. Has taken opium in moderate doses, but has become worse. Pulse almost imperceptible, skin covered with cold clammy perspiration, face deadly pale, lips blue, hands tremulously grasping the air, the eye expressive of great fear, the mind gone, incoherent muttering. Tr. digitalis 5ss was given, in a few minutes the pulse was felt more easily. No sleep occurred in four hours, but he was rather more sensible, less tremulous and warmer : — the same dose of digitalis was repeated. Three hours later he had had no sleep, but in other respects was improved. A further dose of 5ij was given, making 5x in seven hours. After this he had some sleep, and slept at in- tervals during the nig;ht. The next mornino- he was sensible, his fears had disappeared, the skin was warm, pulse full and regular at 90. Heart's sounds and impulse normal. Bowels open. Urine in natural quantity. After this he took some broth, drank freely of imperial and lemonade, but took no stimulus of any kind, nor any > "Med. T. and Gaz.," Sept. 29th, 1860. 120 DELIRIUM TREMENS. Other medicine. He slept some hours in the afternoon ; the next night was a good one, and the next morning he was almost well, and calling out for a mutton chop. It is sufficiently clear that this case was not one for the tartar emetic treatment whether in large or small doses. Opium in moderate doses had failed, and large ones would beyond doubt have soon destroyed life. The especial indication was for a cardiac tonic, to restore the flagging circulation, and this was well fulfilled by the digitalis, which, as I have elsewhere endeavoured to show, has eminently this property. Had one to treat such a case without digitalis, camphor, ammonia, tr. cinchon. and stimulants would be the best means. In the three cases now recorded we have examples of the three principal characteristics which the disorder may assume : (1) that of inflammatory excite- ment ; (2) that of nervous erethism ; (3) that of asthenia. In the first the overwrought cerebral energy must be calmed by tartar emetic with or without opium in adequate doses, cold to the head, leeches or cupping if necessary. The iced bath has recently been recommended by two American practitioners^ as a potent sedative. They warn however that it may produce depression verging on syn- cope. It is a remedy of the same kind as the cold douche in mania, and like it must be used cautiously. In the second the non-inflam- matory nervous erethism must be quieted by some sedative. Full doses of opium often aff'ect this well, but small or insufficient ones are apt to aggravate the disorder. In some cases where opium has failed chloroform given by the mouth has succeeded. It is ques- tionable whether it should be employed by inhalation. Dr. Corri- gan thinks it highly dangerous in this disease, having known it prove fatal in two cases. It should certainly not be used'if there is the least tendency to failure of the heart's action. Henbane may be used I think with advantage in this form of disorder ; 9j should be given at once, and subsequently gr. x 2dis Jioris, till the pupils are dilated or sleep is produced. In the third form the great dan- ger is from the tendency to death by asthenia, which requires some form of stimulants. At the same time the brain may be so irri- table that there is risk of its being injuriously affected by the very means which are necessary to maintain the circulation. Digi- talis itself is perhaps as little likely to do this as any tonic, but in two cases mentioned by Dr. Mackenzie it had the eflFect of changing a state of timidity into the fury of acute mania, and in one I observed myself (large doses being given) it acted similarly. Where it acts favourably it must tell more on the sympathetic ganglia and nervous centres influencing the heart than on the hemispheres. I believe it to be more appropriate than opium to conditions of marked asthenia, as there is decidedly risk of the latter still further depressing the heart's action, while digitalis has the reverse eflFect. It is hardly necessary to say that digitalis would be altogether un- ' "Amer. Med. Times," March 8th, 1862. DELIRIUM TREMENS. 121 suitable for a case of sthenic delirium tremens, with fierce delirium and inflammatory excitement. Hanbury^ relates a case of delirium tremens where digitalis given to the amount of 5vij in a few hours succeeded completely after opium had failed. The indications of asthenia were well marked. Before sleep ensued the patient became rational and laughed at his illusions, and the nervous agitation which had been excessive subsided completely. M'Rea^ states that he has given the digitalis treatment an extensive trial, in eighty cases of mania and delirium tremens. He reports favourably of it. Of 37 cases 3 died, 2 with arachnitis and effusion. Carey reports^ four successful cases by the same method ; in all opium had been given without good effect. From the above exposition it must appear how necessary it is to exercise a sound discrimination in treating a case of delirium tre- mens, and how injurious any mere routine proceeding is likely to be. Probably few things are more difficult than to judge correctly of the vital condition of that vast accumulation of delicate cell-growth which forms the cortical substance of the hemispheres. No appreciable sign that we know of indicates it certainly. The pulse is no sure guide, a weak pulse by no means always indicates a state of cere- brum that will tolerate stimulants and tonics ; and on the other hand a pulse may have much apparent force when these are urgently needed. A cool or moderately hot, and clammy state of skin, a languid lustreless eye, pale and copious urine very deficient in phos- phates, and a timid delirium are we think the signs most indicative of a state of nervous system which will tolerate and be benefited by a stimulant and tonic treatment. Believing as we do that delirium tremens, except in cases of acute occasional excess, is much more than mere alcoholic poisoning, we cannot doubt the propriety of administering judiciously the ordinary so-called stimulants. If the system appeared to be in a state requir- ing them, we should sanction their use without any reference to the causation of the disease. If there appeared no necessity for them, we should certainly forbear them. With regard to the expectant method, we have no doubt that it will afford better results than any blind routioe treatment, but we fully believe that a well-directed medication is far preferable. We cannot think it a matter of indifference whether a patient is allowed to go on raving for a week or more until sleep naturally comes, or whether he is speedily calmed and put to sleep. Nor do we think it can be other than injurious to allow a patient to continue for days with his brain in a state of semi-inflammatory excitement, when we have positive evidence of the power of tartar emetic to control it. In most diseases it is better to trust the unaided powers of the " vis medicatrix" than to interfere blindly and rudely, but this does not lead us to conclude that medi- 1 "Madras Q. J. of Med.

Smith's care, who kindly gave me the following particulars respecting hira. For the last year he has been in a very excited state, at intervals drinking to excess spirit, beer, and large quantities of port wine. Generally after these bouts he has been exceedingly violent, so that his wife has beeu. obliged to fly for her life into the street. He has no sleep at night sometimes for a fortnight, has strange fancies about the inconstancy of his wife. He has always been eccentric, and has an uncle who is said to be out of his mind and subject to fits. Some time ago he had a fit of apoplexy and has been more excitable since. The cause of his last attack was its being hinted to him by a malicious woman that his suspicions of his wife were well founded. He became extremely excited and violent, broke all the furniture in the house, and threw the milk (he is a dairyman) into the street, &c. Mr. S. on being called in gave him tr. hyoscy. 5ij + spt. £eth. chl. Tr\,xx, mist, camph. ^ij at once, and an .li more of tr. hyoscy. in the next twelve hours. He was calmer afterwards, but did not sleep. The next day he was very outrageous and was removed to the hospi- tal, where he came under my care. He was not violent then. Pulse quick. Skin moist. Tongue coated. A good purge of calomel and jalap was given, and in one hour after gr. xv of extr. hyoscy., after which he slept for two hours. He had not slept before for three or four nights. The next day he had 5ss in three doses, and as much the day after, the pupil became dilated, and the throat quite dry. He was very fairly quiet immediately after the first dose of henbane^ slept well on the night of 19th, and was quite recovered by the 21st. It seems to me pretty certain that this man was tranquillized to a great extent by the henbane, and that it was of great value in thus pro- curing the gradual subsidence of the cerebral disorder. He had on former occasions been fourteen days without sleep, and now he was convalescent in about half the time. No. 33. — J. G., £et. 45, ad. May 31st.

The state of excitement of the spinal cord constitutes the disease called tetanus. It seems to me impossible to regard this otherwise than as a functional disorder, although I am quite aware of Demme's researches confirmed by Flechner and others as to the presence of new growths of connective tissue in the cord in various fatal cases which they examined. It seems to me by no means improbable that this new formation was rather the result than the cause of the dis- ease. Just as the Pacchionian granulations result from repeated excitement and hypersemia of the brain, so we may believe that a condition of violent excitement of the cord would very probably lead to some similar effusion in its substance. Moreover the same fibroid formations have been met with in cases of ataxic locomotr., a very different disease. The unpractical character of Demme's results appear in his recommendation of pot. iod. as a remedy more likely to be useful in tetanus than any other. This will hardly meet with the assent of any experienced man. The functional nature of tetanus appears also from its being induced by the poisonous action of strychnia, which, according to the testimony of Todd and Bowman, produces no discoverable change in the nerve tubes and cells of animals killed by it. The curative action of aconite which appears to be the physiological opposite to strychnia may be cited as having the same import. The tolerance of this drug in tetanus is very remarkable, and clearly shows that the system must be in a very opposite state to that which it induces. The effects of long-con- tinued heat as a predisposing, and of exposure to cold as an exciting cause also go to show that the disease is essentially functional. These are common causes of nerve disorders, and it is not surprising that they should be of this. Heiberg^ concludes that tetanus is not a nerve disorder, but an affection of the blood localizing itself in the muscles. This localization expresses itself by deposits in the muscular tissue and metamorphosis of the same probably directly induced by altered or diminished innervation. The immediate result of this is shortening and stiffness of the muscles; the tetanic convul- sions are consequently not spasms, but contractures. The reflex spasms which he admits do occur are only accidental, and do not belong essentially to the disease. He compares the disease to diphtheritis, and recommends the local application of argenti nitras, • "Norsk Magaz.," xv., 1861. 124 TETANUS. or iodine naphtha, or nitromuriatic acid baths. A theory which seems much more probable than Heiberg's, maintained bj Richard- son, Roser, Wells, Thomson, and Betoli, regards tetanus as the result of a poisonous matter formed in the blood, or absorbed into it from an unhealthy secretion of the wound. This acts like strychnia, setting up that peculiar irritable state of the cord which is the essential condition of the phenomena, and without which the various slight excitants which produce the spasms would take no effect. The supporters of this theory justly insist on the prime necessity of accounting for this condition of exalted polarity, which they think can hardly be explained on the sole view of peripheral irritation. They insist further that it gives an explanation of the idiopathic form, and of the occasional epidemic or endemic prevalence of the disease. They notice also the close resemblance between hydro- phobia, a disease undoubtedly of toxic origin, and tetanus. It may also be added that division of the nerve proceeding from the seat of the injury in traumatic tetanus has by no means proved so fre- quently successful as one would expect on the view of peripheral irritation being the sole and essential cause. There is much in this theory to commend it, but until it is proved that any secretion of a wound can on being inoculated give rise to tetanus it must remain a mere hypothesis. We have no example of any similar morbid production setting up notable nerve disorder. In glanders and farcy, in malignant pustules, in pyaemia, in syphilitic and smallpox inoculation, and in the action of snake poison, the phenomena are much more those of disordered circulation and blood crasis than of nervous derangement. It is certainly extremely rare if it ever happens that a foul ulcer, not the result of traumatic injury, becomes the cause of tetanus. On the other hand, the theory which assigns to local irritation the chief place in the causation of the disease has, especially if some- what modified, much evidence in its favour. The well-known greater tendency of lacerated wounds to be followed by tetanus is very strongly shown by Mr. Poland's figures. He states that at Guy's Hospital the disease occurred only in 1 case out of 1364 when the wound was made by a clean sharp knife, but in 1 out of 55 when the nerves were injured as in accidents. Dr. Macleod^ relates two cases of fatal tetanus in which the spasms were almost entirely limited to the side injured. It is clear that in all cases a certain predisposition of the cord must exist before the spasmodic symptoms declare themselves. As Dr. Watson says, " the real mystery lies in this predisposition." It will tend to throw some light on this dark subject if we look at some of the points of aflSnity between tetanus and other nervous disorders. Prolonged exposure to heat is known to have a considerable influence in promoting the occur- rence of tetanus, and. that it enfeebles the nervous system and ' "Notes on Surgery of Crimean War," 1858, pp. 165 — 161. TETANUS. 125 renders it more liable to a variety of derangements is also notorious. Exposure to wet and cold is a recognized cause of tetanus, and from a history recorded by Maisonneuve we learn that it may produce epilepsy. Eighteen sailors after escaping from the enemy by swim- ming to a rock were for seven days exposed to great privation and severe cold ; four weeks after they had been received into a hospital they were seized with epileptic attacks, and in twenty-eight months fourteen died. The action of cold in producing cramp, sometimes pretty severe, even in healthy persons, is a familiar fact. It has caused the death of swimmers. There can hardly be any question of poison here. Yet cramp is a minor tetanus. When tetanus supervenes on exposure to cold and wet, this is perfectly analogous to the invasion of paralysis under similar circumstances. Such paralysis as we have seen is of inhibitory, and therefore of functional character. It is true there is a wide difference between the two results, between the spasmodic and the paralytic affection, but there is much to justify the view that both may be varieties of deranged action of nerve-cells. Just as numbness and pain, which are cer- tainly very different sensory disorders, are co-products ef the cause giving rise to neuralgia, so it may be with spasm and paralysis. In a case of brachial neuralgia now before me the patient suffered at night after about two hours' sleep with unbearable pain and com- plete stiffness of the hand. This was the case after any hard work, but when she had a quiet day she experienced only numbing and tingling pain at night. The affection yielded to quinine and iron. If prolonged action of our muscles causes fatigue, the same when one position is maintained for a long time causes cramp. These facts go to show that causes producing impairment of nerve-power may give rise to spasm. To the same effect is a case recorded in the Brit. Med. Journ., Nov. 29th, 1862, where it is stated that the removal of an osseous nodule from the right thyroid of a young woman cured her both of aphonia and dysphagia (palsies), and also of a spasmodic affection of the arm. In some instances of non- organic paralysis there is rigidity of one limb and simple immobility of the other on the same side, the same cause having given rise to both conditions, and the same treatment removing them. V. Moodeen SheriiF, on Contraction or Kigidity of the Muscles in Paralysis ; 3Iadras Q. J. of Med. Sc, April, 1863. The following history is of much interest in many respects, and especially as showing how an influence which generally tends to enfeeble and paralyze may produce an (apparently) opposite effect : — No. 34.''— Mrs. S., £et. 22, had had "dead ague" a little before April, and expected her second confinement in July. At the age of 14 she had fits brought on by excessive fright in which she had bitten her tongue. April 19th. She had a severe seizure of emprosthotonos, the limbs and trunk being in a state of rigid spasm, and the hands firmly clenched. This lasted ' "Lancet," Sept. 27th, 1862. 126 TETANUS. half an hour, and then changed to opisthotonos, which lasted three-quarters of an hour. Severe congestive head-pain followed the attack. She was purged with calomel, took quinine, and the next attack was much modified as well as the consequent congestive headache. One or two other attacks occurred from neglecting precautions, but by taking quinine, and attention from time to time future ones were averted. She went her full time and was delivered of a living child. Before the first attack she had previous threatenings on two or three consecutive days, and always at the same hour. The district is malarious. Rabe* has recorded the case of a child four months old, who had epileptic convulsions and hemiplegia of the right side with deafness of that ear, and distortion of both eyes to the left. Otorrhosa ex- isted, but the membrana tympani and the walls of the meatus were not materially injured. All these symptoms ceased after the removal of the body of a centipede from the auditory meatus. A similar case is recorded by Fabr. Hildanua, where a piece of glass in the same situation gave rise to similar phenomena. Here we have examples of the production of spasm and paralysis by the same cause in the same system. Chorea, which seems to stand intermediate between tetanus and paralysis, is sometimes excited by terror like the former. Epilepsy, like tetanus, requires a certain predisposition, a peculiar irritability of certain nervous centres. Without this, exciting causes known to produce the disorder fail to take effect. The case which Pfliiger quotes from Dieifenbach shows that a tetanoid state of one arm, and general epileptic paroxysms may be co-results of the same traumatic irritation, and cease with its removal. This indicates that the mor- bid condition in both is diathetic rather than toxic. Dr. Prichard^ states that conversions of chorea, epilepsy, and paralysis are by no means rare occurrences. He cites a case he saw himself of a child who three years ago had pertussis, and the fits of coughing threw her into paroxysms of tetanic epilepsy. These symptoms subsided after continuing some months. She was next seized suddenly with hemiplegia of the right side from which she nearly recovered, but is now troubled with chorea of the same parts. I had recently under my care a girl, get. 16, who suffered from a severe abdominal neu- ralgia, and occasionally from fits of unconsciousness. I saw her in one of these, and found both lower and the left upper limb quite rigid. Under tonics and sedatives she recovered. It deserves I think to be considered that the muscular contractions in tetanus are attended with severe pain, the pain of cramp. JSTow this shows of itself that they are very different from voluntary muscular contrac- tions, which how forcible soever are never painful. The association of pain approximates the nerve disorder to neuralgia. The case related by Swan seems to put in a clear light the influ- ence of an injury in inducing tetanus. The patient, a female, had been operated on for popliteal aneurism by opening the sac, and applying a ligature above and below it. Everything went on satis- ' "Gaz. des Hopit.," 123; 1861. 2 "On Diseases of the Nervous System," p. 64. TETANUS. 127 factorily until one day the attempt was made to change the position of the limb from the flexed to the extended, when the patient uttered a tei'rific scream, was soon after attacked with tetanus and died. At the post-mortem it appeared that the cutaneous nerve which accompanies the lesser saphenous vein had been divided in the ope- ration, and that the upper end which had become adherent to the surrounding parts had been abruptly separated in the attempt at extension. Romberg, who quotes the case, weakens its force by the remark that tetanus must have been already making its approach ; but I think this is not a fair comment on the facts. The case seems to be an example of the effect of shock. Langenbeck' records three cases which go to prove that tetanus may be dependent on local irri- tation. In the first he removed by an incision the fragment of a needle, the symptoms immediately lessened, and next day the patient was well. In the second removal of a ligature from the spermatic cord, which had been tied en masse after castration, at once stopped all the symptoms. In the third case the reduction of a fracture which was attended with great displacement had the desired effect. In examining any case of tetanus we ought to bear in mind the investigations of Froriep,^ who found in seven cases the nerves pro- ceeding from the injured part to the spinal cord affected at intervals with a peculiar inflammatory change, consisting in nodulated tume- faction and reddening of isolated points separated from one another by healthy tracts. He thinks these are peculiar to tetanus. Lus- sana's statement'^ goes to confirm this, who makes one of the points of diagnosis between neuralgia and neuritis that in the latter the muscles are affected by severe and violent, continuous, tonic and clonic, tetanoid contractions. Mr. Erichsen also says that he has never failed to find the nerve running from the wound more or less inflamed, and often for a considerable distance, whenever it has been carefully looked for. The nature of the effective cause in some cases of tetanus makes it most highly probable that no poison was concerned in its production. Such injuries as the blow of a whip- lash, the bite of a finger by a sparrow, the cutting of a corn (Wat- son), can scarcely be supposed to have any toxic action. To give this argument more weight it should be contrasted with the circum- stance that the most various kinds of ulcers so far as I am aware never give rise to tetanus. Syphilitic sores primary and secondary, tuberculous cavities, the intestinal ulcerations of typhoid fever and dysentery, varicose ulcers of the legs rarely if ever have this result. Yet it is surely probable that a poison might be generated in them which would give rise to tetanus if this were the true pathology of the disease. Moreover, in various cases tetanus has commenced some time after the wound, which may have been but a slight one, ' "Med. Centr. Zeit.," 1862, No. 34; " Syd. Soc. Year-book," 1863, p. 220. * V. Romberg, vol ii. p. 104. ' Prize Essay, Milan; Scbmidt's "Jahrb.," vol. cviii. p. 168. 128 TETANUS. has healed. The general bearing of all this seems to be that the influence of shock, or irritation, or of some morbid surface impression is much more potent in producing the disease than any condition ■which might generate a poison. The acknowledged influence of sudden variations of temperature, of mental emotions, and of certain epidemic constitutions in producing tetanus, seem to me to approxi- mate it much more to maladies depending on imponderable agencies, than to the so-called zymotic. Trousseau describes under the name of tetanilla a disease allied to tetanus, and which in grave cases passes into it. It consists in contraction of the hands, arms, or lower limbs, one or all being aff'ected, but the upper being usually the first to suffer. The attacks are preceded by formication, anaes- thesia, and impairment of voluntary power in the limbs, and are attended with more or less pain extending along the principal nerves, and radiating sometimes into the trunk. In grave cases the whole body becomes involved, and there is some amount of pyrexia. It is characteristic of the disorder that the spasm commences in the limbs, and extends subsequently to the muscles of the trunk and neck, contrary to what occurs in tetanus. Further the muscles of the limbs and those of other parts are seldom attacked at the same time, and what is specially distinctive is that the contractions can be brought on immediately by compressing the nervous trunks or the vessels of a part. The most effective causes of the disease are lacta- tion, diarrhoea, attacks of cholera, and of enteric fever, and exposure to cold. It is however remarkable that the application of cold to the contracted parts often immediately arrests the spasm as long as it is continued. Trousseau regards the disease as of rheumatic character. He finds bleeding from the arm or cupping along the spine, where the strength of the patient permits their employment, to have most efficacy. Quinine is the next most useful remedy, and then follow opium and belladonna in small doses. In violent parox- ysms chloroform inhalation may be cautiously used. Aran has found the internal administration of chloroform beneficial combined with its local application to the contracted parts.^ As to the therapeutics of tetanus, it does not matter which view we adopt of the pathology of the disease. If the symptoms depend upon a poison, we have no means of eliminating it, or destroying it in the body. Our efforts are confined in this as in all other cases of the same kind to counterworking the morbid action. Certainly it will always be desirable to promote, as far as possible, a healthy state of the wound if there be one, to correct a faulty state of the secretions, and especially to provide for an ample supply of pure, cold, fresh air. The importance of this in preventing pysemia and hospital gangrene is acknowledged, and I am sure its sedative influ- ence on undue nervous excitability can hardly be over-estimated. I should be inclined to ascribe the recovery of the soldier whose case * "Clinique Med.," vol. ii. p. 107. TETANUS. 129 is related by Dr. MacGregor,' as much or more to free exposure to the fvesh ah', as to the effect of cold, which, except under proper management, is apt to be injurious. Cold aifusion, however, is said to have proved useful, and Dr. Todd recommends the application of ice along the spine. Carpenter^ affirms that he cured sixteen out of seventeen cases by this means. Probably the cold douche would be beneficial. Careful examination of the wound should be made to detect any foreign substances which might be lodged in it, and act as a cause of irritation. A highly interesting case has lately been recorded by Mr. Wood^ where division of the internal saphenous nerve, which was irritated by a comminuted fracture of the leg, arrested permanently the tetanus which had set in two days before with severe convulsion. Dr. Fayrer, of Calcutta, divided the median nerve in a case of wound of the hand with decided advantage." Should any evidence of neuritis be discovered in the course of nerves proceeding from the injured part', this state should be the object of treatment. The exhausting nature of the disease should be kept in mind from the first, and wine and nourishment should be freely ad- ministered. Among the special means which may be employed in the view of subduing the abnormal excitability of the cord there are but very few that have any real chiim to notice. Recoveries have taken place under many, but the share of the drug in the recovery is open to question. With regard to the angesthetics, chloroform and ether, Thamhayn^ reports that they certainly afford considerable temporary relief. The pulse falls to its normal frequency, and the breathing becomes regular. The spasms and the concomitant pains vanish, as well as the distressed expression of the countenance, and tranquil sleep ensues. The external appearance of convalescence is complete, but all the while the disease is powerfully and insi- diously advancing onwards towards its fatal termination. Its course is not delayed, nor its intensity diminished. As soon as the remedy is omitted the whole array of fatal symptoms reappears. Often the intensity of the disease, and of the pain is proportional to the time during which both have been suppressed by the anaesthetic. Saurel's report is in a much more favourable strain; he states that he has procured recovery in 29 cases by chloroform or ether, 11 of them being idiopathic, and 18 traumatic. He thinks the chief cause of failure lies in having recourse too late to these remedies. The pos- sibility of restoring the power of swallowing by these means is cer- tainly a great gain. The conclusions arrived at in a report on 43 cases in the Medical Times and Crazette, June 17, 1854, are nearly to the same effect as Thamhayn's.

There is some ground for believing that ether gives more favourable results than chloroform. With regard to the various narcotic drugs which have been employed, it appears from a review of the cases recorded in various journals during the last four years that aconite and nicotine are the most successful. Woorara shows only two recoveries out of eight cases in which it was tried. One point which seems note- worthy is the great tolerance of aconite which is produced by the disease, a dose being well borne during its continuance, which proves poisonous when it has passed away. The aconite may be given at the rate of i^lxv of the tincture (Pharm. Brit.) 4tis Jioris, of course, watching carefully its effects. It is as well to give it with a stimu- lant, as in brandy-and-water, to obviate its depressing effects on the heart's action. Some systems are extremely susceptible of its toxic effect. I am acquainted with an instance where so small a quantity as half a drop of the Pharmacopoeia tincture (1851) applied to the mucous surface of the lower lip produced distinctly poisonous symp- toms, which continued nearly twenty-four hours. The dose of ni- cotine varies from ^ij to ^ijss, given from four to six times a day, according to the urgency of the tetanic spasms. Its effects are stated to be lowering of the pulse, in one case from 130 to 88, in another it caused an increase of 10 beats; immediate relaxation of the spasm of the muscles of expression, respiration, deglutition, of those of the back and of the abdomen ; cessation of delirium and feeling of relief from agonizing pains ; profuse sweating with an intolerable odour of snuff; tendency to sleep. The hamstring and abductor muscles were more refractory to its influence than the others. Mr. TufnelP records a case of severe traumatic tetanus in which 56 drops of nicotine were given in six days. Chloroform had been given by the mouth for three days without benefit. The nicotine certainly seems to have been beneficial, but had ultimately to be given jjer anu7n owing to the disgust it produced. The teta- nus ceased in fifteen days. The reporters of the Medical Times and Gf-azette, April 6, 18G1, recommend the free use of quinine in all except the most acute cases. The bowels should be effectively acted on once. The diet should be such as to support the strength ; easily-digesti- ble food and wine should be administered at short intervals. Trial should be made in all cases of the continuous galvanic current trans- mitted along the spine. A Pulvermacher's chain of 120 links may be used, or a series of 15 to 20 cells of Daniell's battery. Of course it is not to be supposed that more than a very small part of this current actually reaches the cord, which lies so surrounded by moist tissue capable of transmitting electricity, and this is a reason for employing a larger battery than would be requisite if it were possi- i Dublin Med. Press, Jan. 7, 1863. CATALEPSY. 131 ble to act on the cord directly. It appears that the direction in which the current is passed is of no importance. Dr. Radcliife states that if a frog be poisoned with strychnia it is possible to pre- vent the development of the characteristic spasms, or to suspend them after they have actually commenced, by subjecting the spinal cord of the animal to the action of a continuous galvanic current. Moreover, Matteucci refers to the case of a man suffering from tetanus in which the patient was able to open his mouth, to breathe freely, and to move his body and limbs without much difficulty so long as a strong galvanic current was made*to pass continuously along the spine from the occiput to the sacrum. As regards prognosis, the following may be stated. The later the disease commences after the infliction of the injury the more hope there is of recovery. Prolongation of the disorder is generally hopeful, but it has been known to terminate fatally after fourteen months (Meadow's case).' Continued difficulty of swallowing or hindrance to respiration are perilous signs — death mostly occurring from exhaustion or asphyxia. CHAPTER XII. CATALEPSY. This rare and curious affection doubtless belongs to the family of functional nervous disorders. It occurs chiefly in those who have weakly and excitable nervous systems, feeble health, and ill-governed minds, and who may be said to possess neither a "mens sana," nor a " corpus sanum." In fact many subjects of these disorders claim more properly the care of the alienist than of the ordinary physi- cian. At least it may be said that after the cessation of the actual attack judicious moral treatment will almost invariably be of as much, if not more consequence than medical. One case is however recorded^ where it seems to have resulted from an intracranial epi- thelioma. As regards the nature of the disorder it may be said that it is evidently allied to tetanus, but differs in the circumstance that the brain is involved as well as the cord, and that consciousness is more or less in abeyance. In a case very ably recorded by Mr. Jones^ it is stated that all the muscles of the extremities and of other parts were so rigid that they could not be moved for two or three hours, and in three other cases which he refers to occurring under the observation of others the same symptom was well marked. " The extreme degree of rigidity," he says, "generally exists about the ' " Medico-Chir. Trans.," ISfll. 2 Canst. " Jahresb.," 1861, toL iii. p. 77. 3 "Brit. Med. J.," June 6, 1863. 132 CATALEPSY. commencement of the attack and passes off before the termination." Recently an account has been published' of an endemic cataleptic disorder prevailing at Billingshausen near Wiarzburg. The popula- tion consists of peasants who are well off, but Avho intermarry very much, and are all small and deformed. The affected individuals constitute half of the number, males as well as females. They are called there "the stiff" ones" {starrefi). A chill is commonly said to be the exciting cause of the attacks. The patients are suddenly seized by a peculiar sensation in their limbs, upon which all their muscles become tense, their countenances deathly pale, they retain the posture which they first assume, their fingers are bent and quiver slightly, and the eyeballs in the same way, the visual axes converg- ing ; their intellects and senses are normal, but their speech con- sists only of broken sounds. The attack ceases in from one to five minutes, and the body becomes warm. The indications of a tetanoid affection are very evident here both in the arterial and in the volun- tary muscles, and the same is true of the following case recorded by Mr. Austen.^ " A male, the subject of large delusions and markedly dilated left pupil, having once apparently recovered was readmitted. He was now depressed •and apprehensive. On the sixth day he became heavy, and was got to bed with difficulty. Half an hour afterwards he was completely comatose and motionless ; the pulse was scarcely perceptible, and could not be counted. A salt injection having been given, he was placed on the night-stool, and then it was at once discovered that he was cataleptic. His limbs remained exactly as the attendant left them ; his figure without support was as erect as a statue. The legs and arms were put in positions the least convenient and the most opposed to gravity : thus the legs were ex- tended straight from the hips, and the arms at right angles to the thorax. In tjiis singular state and posture he remained a quarter of an hour, when suddenly the enema operated, and the utensil was filled with an immense number of hard fecal lumps. The pulse on the instant rose, the rigid limbs fell, and the statue vanished. In twelve hours he was sensible, and understood questions. In thirty- six hours he was walking about as usual. This case illustrates ex- cellently the effect of intestinal irritation in producing quasi-tetanic affection of the voluntary muscles, spasm of the cerebral arteries, and probably of the radial. If the latter was not the case, there must have been inhibitory depression of the heart's action. Either might result from reflected morbid stimulus. In the Billingshausen cataleptics it is pretty certain that spasm of the branches of the external carotid existed during the attacks, but not of those of the internal. In other instances, according to Dr. Copland, there is evi- dence of active congestion of blood in the head. In any case as in Mr. J.'s where sudden complete unconsciousness with tetanoid rigidity of muscles occurred I cannot think that the brain could be ' Schmidt's " Jahrb.," vol. csx. p. 301. ' Austen on General Paralysis, p. 55. CATALEPSY. 133 otherwise than an?emic. In a case recorded by Dr. Bellingham {DiihJin 3fed. Press, July 8. 1846) a female, £et. 18, amenorrhoeal, had for more than six months daily fits in which the cheeks were flushed, the limbs almost tetanically rigid, the pupils mobile, the heart's action violent, pulse 120, respiration tranquil. There was complete unconsciousness and loss of voluntary motion, no recollec- tion of what occurred during the fit. After the first ten minutes of the attack the tetanic rigidity diminished, and the limbs could then be placed and retained in any position. She w^as cured by leeches to the nares, purgatives, spt. ammon. foetid., and shower-baths. In the three cases to which Mr. Jones refers consciousness Avas but partially abolished, and the same is true of his own case. The degree of unconsciousness may vary with the degree of anaemia of the hemispheres which is produced. In two of these cases the temperature was not materially altered, in one the surface every- where was of icy coldness, the countenance pallid, and the muscles were rigid as iron, while the pulse was of fair strength. The patient •was a stout male, well made, but of nervous and excitable tempera- ment. He had two attacks exactly of the same kind at an interval of about eleven months, both of which were brought on by the same conditions, viz., excitement, fatigue, and want of food. They subsided after lasting about twenty-four hours by means of rest, •warmth to the feet and the epigastrium, and an opiate (in one).' On two subsequent occasions after a day of unusual fatigue he became very restless and troublesome, very stubborn, and partially insensible, but had no cataleptic symptoms. He was soon restored by rest and an opiate. I have cited some of the details of this case because they seem to illustrate very well how causes of exhaustion may give rise to excitement and violent muscular action instead of, as they ordinarily do, producing languor and prostration. In this young man on four several occasions the same cause was followed by the same or similar effects, the chief diiference being that the brain alone appeared to be affected in the two last. In the chapter on Tetanus I have remarked on some facts analogous to the above, and will only add here that they are all probably ultimately refer- able to the general law that debility of nerve-tissue often coincides "with increased excitability. Catalepsy evidently is a disorder intermediate between epilepsy and tetanus, "with both of which it has affinities. It resembles very much the variety of epilepsy termed tetanic. The peculiar qualities of nervous tissue in different individuals which determine the special form and manifestation which dynamic disorder shall assume are far beyond our observation. One thing, however, we can see, viz., that much depends on which group of nervous centres most readily takes on morbid action. If it be the spinal, we have tetanus ; if the medulla oblongata and adjacent superior region, we have epilepsy ; if the 1 Case of Catalepsy by J. Buclianan, Esq., Glasgoiv Med. Journ., 1857, 1858. 134 EPILEPSY. mesocephale alone, we have so-called hysteria ; if the hemispheres alone, we have "le petit mal" of epilepsy, or " congestion apoplecti- forme c^r^brale." Two or perhaps more of these centres may be affected simultaneously and the resulting disorder will be complex, which appears to be the case in catalbpsy. Treatment must have for its object the removal of existing excit- ing causes (as in Mr. Austen's case), and the calming of nerve irritation. The latter will in some instances be best effected by sedatives, in others by diffusible stimulants. In conditions of great rigidity and coldness of surface a warm bath, or still better wet packing would be I think very beneficial. In prolonged cases galvanism should be employed, and I should prefer using the con- tinuous current first. In Mr. J.'s case the interrupted current materially diminished the rigidity of the muscles, but the cold douche was rather injurious. CHAPTER XIII. EPILEPSY. There can be little question that epilepsy is primarily and essen- tially a functional malady. Graves records a case of great severity in which idiocy and paroxysmal mania had supervened for years before death, but where not the slightest deviation from the normal condition of the brain and cord could be discovered on a very careful post-mortem examination. It is true that minute microscopic research was not employed, but I more than doubt whether this can be trusted to detect changes which give no sign of their presence to the experienced eye. When it is apparent that some kind of change has taken place the microscope may give us most valuable aid in determining the nature of that change, but I am not inclined to trust it for much more. The various alterations which have been found in the cerebral hemispheres and their membranes, the indura- tion of the white substance, the adherence of the gray to the invest- ing pia mater, the dilatation of the bloodvessels, &c., are certainly rather consequences than causes of the paroxysms. One of the most recent and successful investigators of this disease, Schrceder v. der Kolk, states that we " have sufficient reason to conclude that the first cause of epilepsy consists in an exalted sensibility and excita- bility of the medulla oblongata, rendering the latter liable to dis- charge itself on the application of several irritants, which excite its involuntary reflex movements." Even when commencing dementia has shown itself, as evidenced by a high degree of silliness and dulness, complete recovery may ensue. EPILEPSY. 135 The causes -wliicli induce epilepsy are partly physical, partly immaterial. A great number of lesions about the head and even in remote parts are known to have given rise to the disorder. Such are injuries to the cranial bones, cicatrices of the scalp, tumours in the meninges, wandering wisdom-teeth, worms in the bowels, calculi in the ureter, or bile-duct. The disease originated in this way is termed eccentric. It should, however, be clearly understood that these physical excitants are by no means mere provocatives of the paroxysms, the convulsions being supposed to ensue as the reflex results of irritation, but that they actually set up in the nervous centres that state of excitability which is the essence of the'disorder. They are therefore both predisposing and exciting causes. They require, however, a certain amount of predisposition in the nervous centres to become operative. In many individuals the quality of these centres is such that the morbid impression fails to take effect, they are proof against it. In others, and this is very remarkable, the same cause which might have induced epilepsy has a different result. Thus intestinal worms may cause paraplegia or amaurosis, a neuroma may cause only severe neuralgic pain, and an exostosed wisdom-tooth permanent infra-orbital neuralgia. Causes of centric epilepsy are the following : Poisoning of the blood from retention of excrementitious matter. This by deranging the nutrition of the nervous tissue generates the abnormal excitability which then mani- fests itself without any special irritant. Various causes of exhaus- tion, such as hemorrhage and excessive discharges, venereal excesses, prolonged want of sleep, unremitting pain act very much in the same way. Sudden fright seems to rank rather higher as a cause. Copland indorses Esquirol's statement that fits of passion, distress of mind, and venereal excesses hold the next rank to terror in excit- ing the disease. This shows the relation of the malady to chorea, which is so commonly produced in the predisposed by fright. Grief, prolonged anxiety, the sight of a sufferer in the paroxysm, and in fact almost any very powerful mental emotion may give rise to epilepsy. From the above facts one conclusion of much importance may, we think, be deduced, viz., that epilepsy is for the most part a diathetic, and not a toxic affection, and that the elimination of a materies morbi is not to rule our therapy. The effective causes are mainly those which produce dynamic derangement, and which so far as we know can generate no poisonous matter. There is one condition which has not yet been mentioned, and which according to my experience is rather infrequent, but which Copland declares to give rise to the most common form of cerebral epilepsy, especially in this country. I refer to sanguineous plethora. Prichard also in the interesting cases he relates, found repeated venesection so often of essential service that one cannot doubt that an excess of the circulating fluid may be a vei-a causa of the disease. Schroeder v. der Kolk's experience is nearly to the same effect. Copland says that he has found the disease most frequent in persons 136 EPILEPSY. ■who were either very plethoric, or very much the reverse. My own observation leads me to the contrary opinion, I should certainly say that the epileptics I have had to deal with have been of a medium temperament, neither sanguine nor anaemic. With regard to indi- viduals in the latter state, I have often remarked their freedom from epileptic disorder. In some exquisite instances of anemia there has been nothing of the kind. With respect to local plethora, i. e., determination of blood to the head, the case is different. This is often associated with very marked debility, and seems indeed to a great extent dependent upon it. The vaso-motor nerves of the cerebral arteries participating in the general weakness become unable to keep the vessels properly contracted, in consequence of which a relative excess of blood is sent to the encephalic centres, and produces a state of excitement. In some cases the local deter- mination of blood may be due, at least in part, to the state of excite- ment of the nervous tissue induced by other causes, and which then attracts dfronte an undue amount of blood to the part. The condi- tion here is similar to that which exists in .some cases of retinal hypersesthesia, where the morbid excitability is complicated with and aggravated by a degree of hypersemia. The state in fact is one of semi-inflammatory nisus. The irritating effect in certain conditions of an excess of blood coursing through a tissue has not, I think, been sufficiently con- sidered. It was excellently illustrated by Vanzetti in his observa- tions on inflamed limbs, where the inflammation was found to subside permanently after the main artery had been compressed for about twenty-four hours. The following remarks seem to me to set forth the pith of the matter. The circulation of arterial blood not only maintains the nutrition of the several tissues, but also acts as a sus- taining stimulant to their vital powers. Of this I think we can be sure from the phenomena attendant on embolism. A patient is attacked suddenly with violent pain in the left groin, " exactly as if he had been shot." From that moment, so runs the report,^ the limb became numb, cold, and quite powerless, and pain continued intense for some hours, at least twenty-four. Death occurred from gangrene in thirty-seven days, and an embolon three-quarters of an inch long was found in the femoral artery two inches below Poupart's ligament. Now, as the muscles and nerves of an amputated limb manifest their functional power for some short time after its removal, we are sure that the powerlessness in the above and in similar instances did not depend on any immediate abolition of contractility and of vis nervosa, but on an impairment of these vital faculties, so that the organs were unable to respond to the stimulus of the will. Kussmaul's and Tenner's conclusion, that the brain of a rabbit can remain deprived of arterial blood for two minutes without losing its capability of again performing its functions upon the renewal of the 1 "Lancet," June 7th, 1862. EPILEPSY. 137 circulation, the convulsions ceasing immediately at the same time, shows also that nervous centres retain to a considerable extent their vital powers when deprived of blood. In cold-blooded animals this independence of the tissues on continuous circulation of blood is much more marked ; frogs and snakes will certainly perform voluntary movements when circulation has ceased. From these facts, then, as well as from the immediate arousing and exciting effect on the bi ain of an increased flow of arterial blood, while its deprivation as rapidly induces an opposite state, I conclude that blood is not merely a nutrient to the parts it traverses, but also an excitant. Now in plethoric states, whether general or local, this excitation may be excessive, and the so-called excitable districts of the brain, the medulla oblongata and the parts situated just above it, may be thereby wrought into a condition of abnormal irritability, Avhich bloodletting or checking of the blood flow may much relieve. It is of much interest and importance to determine what is the condition of the brain and nervous system for a short time before and at the time of the paroxysms. This seems to have been pretty well settled by observation. Dr. Copland's long list of premonitory symptoms may be summed up in the statement that they all of them indicate a state of abnormal irritability or incitability, associated with a very varying condition of blood-flow, which may or may not be in excess. The due and regular nutrition of the nervous centres is evidently deranged. The aura with which the paroxysms some- times opens is one of these nervous derangements. It is an ex- tremely remarkable circumstance that interference with this aura should in a certain number of cases enable us to arrest the paroxysm which is on the verge of exploding. That the aura is really of cen- tral origin can scarcely be doubted, its appearing to extend along the nerves indicates only the involving of one central termination after another. There is no sort of reason for supposing that there is any peripheral disorder in the nerves which are its apparent seat, and' where there is such disorder, as in neuralgia, it does not concur with epilepsy. It remains therefore a very curious and suggestive fact that we should sometimes be able to modify the vital state of a ner- vous centre, and that too beneficially by acting upon the nerves to which sensations of central origin are referred. Something of the same kind has been observed in sciatica, and in other states. Almost up to the moment at which the paroxysm commences the circulation is not notably disturbed, but just at this time, according to very accordant testimony, marked pallor of the face ensues, followed by the shriek, the insensibility, and the convulsions. The sudden complete insensibility of the "grand mal," the giddiness and more or less complete though briefer unconsciousness of the " petit mal" seem to me capable of being explained only by a suddenly- induced anaemia of the hemispheres ; and the convulsions are, as we know from Kussmaul's and Tenner's researches, necessary conse- quences of the same state of the medulla oblongata and the meso- 138 EPILEPSY. cephele. That the cerebral anaemia is not the result of mere syn- cope we are sure. There seems then nothing left but to assume that a sudden constriction of the cerebral arteries occurs. It is highly probable that the greater the hyperasmia and excitability was just before the attack, the more violently will the nervous centres resent the succeeding anaemia. In the majority of instances the cerebral anaemia is of short duration, and is immediately replaced by a hyperaemia which at first is of venous character, both from the retardation of the blood in the large veins, and also from the non- aeration of the blood wdiich the left heart sends into the arteries. As the respiration is restored the hyperaemia becomes arterial just as was observed in Kussmaul's rabbits. This hyperaemia results from dilatation of the vessels, which seems to be the natural sequence to sudden constriction, as in the common reaction and glow which ensues in healthy persons after the shock of a cold douche. That the sopor depends chiefly on exhaustion is apparent from its absence in cases where the attack consists in simple unconsciousness without convulsions. The foregoing seems to give a rational account of all the ordinary instances of epilepsy, but it may be questioned how far it applies to cases where the paroxysms are unusually prolonged. In many of these the paroxysm is made up of a series of attacks separated from one another by a longer or shorter interval of soporose exhaustion. There seems no difficulty in understanding that the anaemia may recur at the commencement of each, and that thus the same phe- nomena are repeated again and again. It is impossible to deter- mine how long the anaemia (which of course is not complete as it was in Kussmaul's and Tenner's rabbits) may last, nor how long its effects may continue to be manifested by muscular agitation. If indeed the ansemia were immediately replaced by a moderate flow of arterial blood, it is probable the paroxysm would rapidly be at an end. But this is not the case in the fully-developed attack, the disorder of respiration and the remora of the venous current fill all the cerebral vessels with blood that is very imperfectly depurated, and the disorder and commotion of the vesicular neurine continue longer than they otherwise would. Much no doubt depends on the quality of the nervous centres ; if they are highly irritable, and the " vis nervosa" is considerable, the disorder will be more violent and prolonged than when the reverse is the case. Thus, in the later periods of the disease, when the brain has become more or less damaged, the paroxysms are often less severe than at an earlier date. In all instances then of true epilepsy, I conceive a temporary, more or less complete anaemia from spasm of the cerebral vessels, to be the determining cause of the paroxysm, and to give it its spe- cial features. Without this we may have various symptoms of cere- bral irritation, but no epilepsy. A case recorded recently by Dr. Palmer {v. p. 178) is surely an instance which might well have EPILEPSY. . 139 assumed the form of enteric epilepsy, but inasmuch as there was no tendency to arterial spasm the morbid phenomena took a different direction. It is however quite certain that long-continued convulsions may be produced by the irritation of tubercles in the brain, by acute hydrocephalus, by exanthematous miasm, and by certain poisons. In such states there will be no spasm of the cerebral arteries, and no consequent ansemia. The medulla oblongata and other parts of the encephalon are directly irritated, and convulsion ensues, as when the same parts are excited by the touch of the scalpel in a living animal. The chief distinction between epileptiform attacks depend- ing on direct cerebral irritation, and those occasioned by arterial spasm lies in the paroxysmal and intermittent character of the one, and the more continuous character of the other. In any given case of course it will be essential to consider carefully the attendant cir- cumstances, as the state of the urine, and of the bowels, the exist- ence of any indications of intracranial disease, or of commencing smallpox, &;c. In young adults we should not forget the possibility of an errant wisdom-tooth being at the bottom of the disorder. The case which I have given at p. 51 shows however that epilepsy, to all appearance idiopathic and centric, may at its supervention persist through so long a succession of paroxysms as to prove fatal by ex- haustion. It is a question not easy to decide how far arterial spasm without any previous abnormal state of the encephalon may pe7' se give rise to epilepsy. If the disease is ever produced in this way we should expect to find instances of it among the manifold pranks of malarious miasm, and it actually appears to be so. Mr. Lowe says/ " within the last twelve months, many cases of jungle fever, contracted in the Upper Godavery district, have been attended with severe epi- leptiform convulsions." Dr. Payne^ has observed epileptic attacks ensuing as the result of malarious infection, which may have oc- curred long previously, and not have shown itself in paroxysms of ague at any period. Cases of infantile convulsion are frequently seen at Calcutta which stands in very close relation to malarious epilepsy. In all of these quinine affords a cure. Payne considers that a hydrsemic state of blood is the most important element in the pathology of this class of disorder. Dr. Mackay^ recognizes the occurrence of malarious epilepsy, and records a case of the kind, in which the attacks were arrested by quinine. In some of Torti's cases of lethargic pernicious fever the condition during the paroxysm was not unlike that of the epileptic attack. In one case convulsive movements occurred continually, and such a profound lethargy that no kind of painful stimulation had any effect in arousing the patient. The disease was cured by bark. Even in these cases, however, it is 1 "Madras Q. J. of Med. Sc," Jan. 1863, p. 67. 2 "Indian Annals," No. xiv. p. 597. 3 "Edin. Med. J.," Oct. 1863. 140 EPILEPSY. not certain that the cerebro- spinal nervous centres were not to some extent directly and primarily affected by the poison. Now that we know so much more accurately the effects which are produced on the brain by sudden arrest of the blood-flow, it seems to me that very much of the mystery which has long attended on epilepsy is removed. Indeed, so far from regarding it as a very strange and wonderful occurrence, a "morbus sacer," one is rather surprised that it and its allied disordei^ are not much more common.' It is truly a small inconvenience if from long sitting still, or from cold. our hands or feet get benumbed from contraction of the arteries ; as soon as we restore the circulation all is speedily in order again, and no damage is done. But if from any cause our brain gets into a like state, it is no such light matter — the delicate and complicated organ whose function is of so high a nature cannot tolerate the sus- pension of its due nutrition and stimulation so easily as the skin can, and its disordered actions are manifested in the grave derangement of all the functions of the body over which it has sway. Some time ago a child was under my care for some slight ailment, and on one occasion I observed that its arms and hands were livid and cold. I was told that this occurred not unfrequently without any exposure to cold. I could not help thinking, how if the cerebral circulation was affected in a like way ? would not serious symptoms declare themselves ? I cannot but think that many of the peculiarities of epilepsy depend on the peculiar arrangement of the encephalic arte- ries. The large mass of the superior nervous centres is supplied with blood by four trunks which are amply furnished with nerves, and liable therefore to be influenced by them. It is clear that any spasm of these vessels is likely to be attended with much more con- siderable results than where, as in the case of the spinal cord, the vessels are small and numerous, and not likely to be affected many of them at once. The case of retinal hypersesthesia, commonly called scrofulous ophthalmia, is worth considering with regard to the pathology of epilepsy. The disorder is essentially one of debil- ity, a neurosis, at least I can affirm this of some exquisite cases. The debility gives rise to the hypereesthesia according to the general law, and this determines the most intense spasmodic muscular con- traction. It is true this contraction is sub-continuous, but we have instances enough to prove that a permanent irritation acting on the encephalic centres may give rise to intermittent phenomena. So in many cases of epilepsy primary exhaustion sets up a state of undue nervous excitability in the medulla oblongata and adjacent parts which then gives rise to intermittent motor disorder. The treatment of epilepsy and of its kindred states may be de- signated as either empirical or rational. To the former I entertain a decided aversion, yet would thankfully accept any proofs of the ' The divine old man of Cos clearly foresaw this. Hippocrates' Works, Syd. Soc. Edit., vol. ii. p. S43. EPILEPSY. 141 real virtue of remedies, which must be regarded in this light. Alisma appears once to have done good in my hands, but probably it would fail in most cases as it did in the next I tried it. I have no notion of any reasonable ground on which we could expect it to be beneficial. Cotyledo umbilicus has perhaps more claim to notice, but I have had no success in its use. The list of such remedies is endless, and the encouragement to experiment with them but small. Still I think we should not wholly abandon remedies of this class, and in many refractory cases we are sure to meet with we shall do well to follow the example of Dr. J. W. Ogle, and test the virtues of the galium album, and similar herbs. Considerable allowance should be made for manifold idiosyncrasies, which are in all probability more numerous and developed in the cerebral tissue than in any other. Under this head we may allude to the desirable gift possessed by some men, so much more than by others, of inspiring confidence and hope by their mere presence and speech. It is unfortunate that ex- perience does not tend so much as one could wish to develop this quality. The aim of rational treatment is first to remove exciting causes of the disease, if any such can be detected, as worms, misplaced teeth, masturbation, &c. Next we must seek to correct any evident faulty state of the system, angemia, plethora, debility, syphilitic infection, or the like. We may then proceed to combat the especial vice, which is the " fons et origo mali," viz., the undue excitability of the nerves or nervous centres. For this we have various sedatives of considerable efficacy. In violent, rapidly-recurring paroxysms mor- phia, as Dr. Sieveking has shown, will do good service. In ordinary chronic epilepsy belladonna or henbane long and steadily continued is preferable. They should be given in sufficient doses to produce some decided effect. It is common with me to give gr. j extr. bellad. ter die after having commenced with gr. J or gr. \. Henbane may be given in gr. v to gr. x doses of the extract ter die. These sedatives may often be advantageously combined with zinc, tannin, or nitrate of silver; ol. morrh. may also be given in many cases along with the sedative. Counter-irritation by means of an issue in the arm, a seton in the neck, or remote blisters, should be used when there are signs of over-active circulation in the head. The good results obtained by V. der Kolk from the insertion of a seton in the neck, the actual cautery, issues, and cupping are certainly very striking. In some instances considerable improvement of the mental faculties which had been impaired by the disorder ensued on the use of these means. Purging may be advised in cases which are tolerant of it with the same view. On the other hand, we shall meet with many cases where the indication is to tone and invigorate. Here we have to select the least irritating tonics, as tannin, zinc, nitrate of silver, and cod-liver oil. Dr. Anstie has specially commended the latter of late in all chronic convulsive disorders, and I am much disposed to agree with him as to its beneficial action, at least wherever there 142 EPILEPSY. is evidence of nervous exhaustion. He finds it, however, useful even where the general nutrition is excellent. In states of great nervous prostration I think strychnia is of material use, just as it is in chorea. Determination to the head may depend upon loss of tone in the vaso-motor nerves, or the arteries, and tonics may then be the most effectual means of controlling the hypersemia. This is a case, how- ever, in which much tact and judgment are requisite, especially at first, lest the tonics prove irritants to the over-excitable brain. Tannin, which is no mean tonic, has also the very desirable property of constringing the bloodvessels, and on this account is very appro- priate in a disease where there is so much tendency to dilatation of the vessels by repeatedly-recurring congestion. I have heard on good authority of bichloride of mercury having been employed with the best results. The action of this drug is a mystery to me ; by some it is ranked as an excellent tonic, and certainly it is unlike any other mercurial that I am acquainted with. If it be regarded as a mercurial, it would be appropriate, I think, to conditions where, together with increased excitability of the nervous tissue, there was also local attraction of blood, a quasi-inflammatory nisus. That mercury properly employed has the power of annulling this morbid attraction of blood I am convinced. Bromide of potassium is highly spoken of by good observers as a remedy which is of great value in diminishing the number of fits. It will keep them oif for long periods, even for a year, but they are prone to recur when the medicine is discontinued. The dose is gr. v ad xxx ter die. Much importance is attached by several authorities to the arrest of any aura that can be detected, and there seems sufficient evidence to show that the repeated suppression of it may be curative. It occurs, however, only in about half the total number of cases, and when it does occur it is not by any means always in a part where any means of averting it can be employed. Further there is I think some ground for apprehension that it may but prevent the manifesta- tion of the disorder for a time which will ultimately break out w^ith increased severity. Rchroeder v. der Kolk says this is to be feared even with our ordinary drugs, leading even to a fatal result. One sine qud non to successful treatment is that the patient should repose a cordial reliance on his physician, and that the latter should gird himself to a prolonged and difficult contest. Obstinacy on the part of the disease must be met with patient determination not to be discouraged ; and I speak from experience when I say that we shall sometimes achieve good success after we have often been almost ready to despair. The hygiene should be most carefully regulated, and everything should be avoided which can tend to diminish strength and increase excitability. The diet should be simple, but nutritious, cofiFee and tea had better be forborne, or sparingly indulged in. Good malt liquor may be allowed if it agrees, or instead, if need be, a little ■wine. Tolerably robust persons will no doubt do wisely to become, EPILEPSY. 143 as a rule, water-drinkers. Romberg recommends to erethetic sub- jects a milk and vegetable diet. Cold affusion in the form of a morning douche or shower-bath will be serviceable in most cases. As much open-air exercise should be taken as the intervals of the fits will allow, as there is probably nothing which tends more to diminish morbid excitability. The good effect of the exercise will be much enhanced if it can be taken in the pursuit of some interest- ing recreative occupation. To many patients who cannot abandon their occupations it will of course be impossible to carry out these latter regulations completely, but they must be encouraged to do what they can, and reminded of the proverb, "that half a loaf is' better than no bread." To unmarried patients strict chastity of mind and body should be commended, to the married a sparing use of the conjugal bed. This is of course an extremely delicate matter to touch upon, but the effect of sexual indulgence on the nervous system is so considerable, especially in weakly persons, that a medical adviser can by no means leave it unnoticed. That which is quite innocuous to a sound man may be very pernicious to one of epileptoid tendency. In young persons of both sexes the existence of vicious habits must be considered possible, and measures must be taken for the detection of this wretched practice. It is one of the most unpleasant tasks that can befall a medical attendant to have to institute such inquiries, scouted as'the very idea is likely to be at first by the parents ; but too much is known of the prevalence of this vice and of its ruinous effects to allow us in doubtful cases to ignore it. There is abundant room here for tact and discretion, and perhaps the best way of proceeding is for the ordinary attendant to divide the responsibility of the inquiry with another, who appears more as a stranger, and is less likely to give offence. The subject of puerperal convulsions has so much connection with that of epilepsy that I cannot but allude to it here. Not that we can regard the two disorders as identical, for there is evidence to show that epileptic females are by no means prone to suffer from puerperal convulsions. It is plain, however, that while they are different there is a considerable resemblance between them, and that any conclusion we arrive at respecting one must have a bearing on our views regarding the other. Of true epilepsy albuminuria forms no part, while in puerperal convulsions it is almost constant. It is probable that the toxic state of the blood materially modifies the condition of the nervous centres. In true epilepsy arterial spasm plays a prominent part, in puerperal convulsions this is not the case. The latter are in a much greater degree dependent on remote irrita- tion than the former, whether we regard this irritation as acting indirectly through the renal disorder it produces, or directly on the nervous centres, or, as is most probable, in both ways. However, regarding the two disorders as certainly very much allied, the point to which I wish to draw attention is the following — viz., that there exists good evidence to prove that the pathological state giving rise 144 EPILEPSY. to puerperal convulsions may vary considerably from a highly sthenic to an asthenic quality. Excellent authorities testify that copious venesection is a very valuable remedy in many instances as well as nauseating doses of tartar emetic ; while in many others it is admitted that chloroform inhalation tranquillizes satisfactorily the morbid excitement. Sir C. Locock says' that these convulsions " appear sometimes to depend upon a loaded (congested ?) state of the brain ; at other times the brain appears to be influenced by dis- tant irritation either in the uterus or digestive organs ; and again in some cases puerperal convulsions are induced apparently by a peculiar irritability of the nervous system." I cannot but think that these views are very applicable to epilepsy, and that we may aflBrm almost the same of the one disorder as of the Other. At any rate they must be admitted to add considerably to the probability that the essential morbid state in epilepsy may be very different in dif- ferent instances, and may require extremely different modes of treat- ment. I append here a summary of cases of epilepsy. No. 35. — W. B., m., set. 29, had suffered two years off and on with attacks of non-ccnvulsive epilepsy occurring every fourteen days. Has warning by sensations in head for two or three minutes before each attack. Under in- creasing doses of strychnia carried up to gr. jV ^^^' ^*^? the interval was pro- longed to eighty-nine days. No. 36. — S. H., f., at. 16, ad. with convulsive epileptic attacks; last two intervals were fourteen and seventeen days. Catam. regular. Under alisma plantago the interval was prolonged to thirty-four, and again to seventy-one days, at which date she was discharged, having had no return. Admitted again with recurrence five weeks later, same treatment pursued ; — the first interval was thirty-three days, then she had three fits in ten days : — -alisoia was continued and she took beside tr. ferri muriat. ttlx + tr. opii TT^v ter die; the next interval was twenty-seven days, and then the same treatment was continued 100 days without relapse ; she was then dis- charged, and has not, though more than a year has passed, presented herself again. No. 37. — E. B., m., set. 17. Ill four years with epileptoid attacks on ad. ; he has four to sis in the day and many at night. Digestion bad. Alisma of no benefit. Tannin, and subsequently tannin and opium, with at first acid, muriat. -}- acid, hydrocy. dil. and afterwards tr. arnicse was given for eighty-four days with great advantage, so that he was free from attacks in the day, but often had a " touch" at night. For the last six weeks he was under my obsei'vation be did the work of a light place. No. 38. — W. S., m., ^t. 20. Subject to fits seven years, had three fits last week, has usually about twelve a month. His head aches much and gets hot before the attacks, and he has sparks before his eyes. Under extr. bellad. gr. J ter die with mist, ferri laxans he had no fits for eighteen days, and did not attend afterwards. No. 39. — J. N., m., aet. 22. Has had fits for eighteen months, about ^ "Cyclop, of Pi'ac. Med.," art. Puerp. Convulsions. EPILEPSY. 145 two a week generally, but is sometimes a month without any. He took extr. bellad. gr. |- bis die for 105 days, and had no fits all the time, only threat- enings, in which he stated that his hands twitch and start, and his legs get weak ; medicine omitted. No. 40. — E. E., m., ast. 48. Has epileptic attacks at intervals of about one month ; has had none now for ten months. Head cut deeply several years ago by a fall from his box while driving. He was senseless for a week, and had bleeding from the right ear. He seemed to recover from this, but in about two months had a fit partly induced by the heat of the weather, ever since then has been subject to the fits, which occur without warning. There is a cicatrix on the forehead which is adherent to the bone, but not very tender. This cicatrix was blistered, and he took tr. hyoscy. ttlxx ter die, with ol. morrh. 5j- Under this treatment he improved very much, became less nervous, his vision which had been misty got clearer, and no attack occurred. He described himself at the end of sixty-seven days " as a man compared to what he was." Subsequently, however, the attacks recurred. No. 41. — F. B., f., set. 31. A very nervous subject, has fits occurring at irregular intervals ; is weak and trembling. She took strychnia in doses gradually increased from gr. ^V to g^"- i ter die, with iron and liq. opii sed. with great advantage. Subsequently she had tannin with small doses of morphia and argenti nitras. The frequency and severity of the fits appeared to be controlled, and her general condition was improved. No. 42. — A. R., m., set. 11. Ill for a year with fits, recurring at first every two months, but every day for the last week. They last five minutes to an hour. In the fits he bites his tongue, and struggles much. Severe pain in left hypochoudrium after, and is very sleepy. Has lost his speech three months. Health pretty good. Pupil of medium size. Ordered, April 23d, tr. hyoscy. tt^xv ter die and ol. morrh. ^yjer die. May 14th. Two fits since April 23d, the last on 26th. Is much better in himself. Does not speak above a whisper. 28th. Has regained his speech. June 11th. Feels better than he has been for years ; no return of fits. Discharged. He had a relapse in September, and was treated by tr. bellad. 1^5 + ferri et quinae citrat. gr. vj tei' die with ol. morrh. ; three fits occurred from Sept. 24th to 28th, none afterwards up to Oct. 22d, when he ceased attendance. No. 43.— J. P., m., set. 19, ad. Oct 2, 1862. Ill six months, is subject to fits, has had nine. Last interval three weeks. Before they come on he feels unsettled in his head for a day. In the fits he shakes, has singing in the ears and falls down, lies unconscious ten minutes, but it is thirty before he is fully recovered. They occur mostly of a morning. Health otherwise good. Is growing fast. Pulse very small and feeble. He thinks that suppressed perspiration of the feet may be the cause of his attacks, but admits that he has practised masturbation. His forehead on various occasions has appeared notably hot, and the circulation in the skin over-active, while the feet and hands are apt to be cold. At one time, while they were perspiring, he felt much better. The face and ears he describes as burning for twenty minutes at once. He has various other symptoms indicative of nerve disorder, and seems to be rather of a fanciful tendency. His condition is certainly not one of plethora, but is equally remote from anaemia; the most evident abnormality is the irregularity of the circulation, the arteries of the head being disposed to admit an undue supply of blood. Atropine and belladonna did not appear to be beneficial, his head was cooler and quieter while taking extr, hyoscy. 10 146 EPILEPSY. gr. V ter die. An issue in the arm was of no avail, besides much other treatment, including tannin, argenti nitras, and pot. iod. No. 44. — F. L. set. 11, f., ad. Nov. 16th. Had fits when three years old, and was ill a long time, lost all his faculties for a month, and was paralyzed on one side. Recovered and remained well for seven years and free from fits, but since then he has had them at intervals of about six weeks. Two fits occurred in the last week. Becomes quite unconscious in the fits, which always occur during sleep; the following morning he is dull, stupid, has headache, and is very irritable. Head rather hot, has some pain in it now. Large face, red lips, pulse regular, quiet. Some warning is afi'orded of an approaching fit by his being tiresome and irritable the previous day. He remained under observation till Feb. 22d, when he had had no fit for three weeks, previously they occurred about once a fortnight. Tonics and blisters to the neck did not seem of benefit, zinc gave more promise of good. No. 45.— M. S., set. 20, f., ad. Nov. 15 ; ill two days. Had a fit at first, in which she bit her tongue ; since then has had nine or ten fits, but not " insensible ones," left side only affected by the convulsions. Some frontal pain, better when recumbent. Has felt giddy lately, but not weak. Has passed ascarides. Cat. regular. B. open Nov. 18th. The shaking fits in left side continue, and she has temporary loss of power over the arm, leg not affected. The fits occur very frequently, more so at night. In four days the fits had ceased, and Dec. 20th she was discharged, well. The im- provement commenced as soon as she was ordered ferri et quin. citr. -\- tr. nucis vom. A blister applied at first to the neck was of no benefit. No. 46. — J. K., set. 41, m., ad. Sept. 6th. Suffers from nervous debility, which brings on fits ; has been getting worse last three months. For last ten years has not debauched. Looks ill, and his face sunken. Skin cool. Pulse weak. Takes food well. B. regular. Has much pain all over his head as if his brain was on fire. Is subject to attacks of headache, lasting three to four hours, in which he vomits much yellow bile. In evenings, he feels the blood flowing up to his head for two hours, and has dreadful sen- sations 3 at other times it seems as if his life was departing he is so chilly. Every other day he experiences nervous tremblings and low spirits, with fearful apprehensions, which come on worst in the evening. The fits occur at various intervals once a month or oftener; he afSrms that he is more liable to be attacked at the changes of the moon. The fits come on, he says, with palpitation and fluttering of the heart; the blood then flows to the head, and when it has reached a certain part at the back he becomes uncon- scious. This man was highly hypersesthetic, and a very unpromising sub- ject for treatment. Full doses of tonics did not seem to benefit him, but assafoetida gr. x otis horis did considerable good; "a world of good," as he stated. He remained under treatment till Feb. 27th, and had no fits during the last two months. I regret that I did not give him ol. morrh. No. 47. — W. A., set. 53, m., ad. Ill two months. Was at first confined to bed ; was quite insensible at times, and used to talk wildly ; had pain in head ; no paralysis ; no fit ; since then he has recovered a good deal, but is attacked many (fourteen or fifteen) times a day with loss of speech, weakness of limbs, some giddiness. This affection soon passes off, leaving him quite well. While in the consulting-room he had an attack during which he was unable to speak plainly as before. He compares the attacks to a sudden cloud passing over the sun. When they occur while he is walking he has to stop. Pulse weak, languid, 86. Pupils nearly equal, mobile. Syphilis EPILEPSY. 147 denied ; some stricture. No worms passed, not even after a dose of male fern. On one occasion I dilated the pupils with belladonna, and examined the fundus of the eye while an attack occurred, but I could perceive no manifest pallor of the red field. Opium in gr. h doses lis die seemed to check the attacks for a while; afterwards he benefited with strychnia and tannin. His health became better ; he had not to stand still when the fits came on, and they were less severe, but as frequent. This was a well marked instance of "le petit mal." No. 48. — M. A. S., set. 12, f., ad. Jan. 21. Ill one year. Has something like fits in which she is unconscious, and appears as if strangulated ; her eyes water. They occur about once a week. Has often violent pains in eyes and head; sight dim. When six years old passed round worms, but a dose of male fern now brought none away. With tannin she benefited ma- terially, but ceased attendance too soon. Belladonna in small doses, and a seton in the neck, did not seem beneficial. No. 49. — H. W., set. 64, m., ad. June 6th. Subject to epilepsy eleven years from an injury to his head, on account of which he was discharged from the police. No attack for two years till eight days ago. Has numb- ness in right side of face, right arm and hand, and pain down back of right leg. Feels giddy and trembling, and shaky if excited. No pain in head. If he gets up suddenly he cannot see for a time, and everything swims before his eyes. Is a painter now; has dirty teeth, no blue line. Urine quite clear, and normal-looking, not albuminous, sp. gr. 1018. With ammonia, valerian, tr. hyoscy. and tr. nucis vom. and 5j doses of ol. morrh. ter die he recovered from the above symptoms, which were probably sequelae of the attack, and felt almost as well as ever he did in his life. ■ No. 50. — W. H., set. 5, m., ad. Sept. 21st. Ill since one year old with fits which occur at intervals of one to nine months, several often occur to- gether. In the fits he cannot get his breath, is black in the face, and un- conscious ; screams much. After fits, has fever for several days, and is ill for three or four weeks. Last fit three weeks ago. Pulse not weak ; skin hottish. Another fit occurred Oct. 14th. He took tr. ferri mur. with much benefit, and afterwards liq. pot. arsen. and ol. morrh. when some eczema appeared, and improved still further. No. 51. — E. P., aet. 9, f., ad. Oct. 8th. Ill three months with fainting fits, but has struggling fits last fourteen days. She struggles and screams ; complains that her head is coming ofl^; loses consciousness for three-quarters of an hour. The fits begin with drowsiness; she lies down and goes to sleep, in about ten minutes the fit comes on. Had two fits yesterday in the afternoon. Before the fits commenced she used to have pains in the abdomen, and in the side like cramp ; these have ceased. Is restless at night, talking and tossing about. Head not hot; urine rather pale; no appetite for meat. Is weakly. Has scrofulous disease of one foot; not anaemic; tongue clean. Nov. 6th. Appears as if her intellect was affected; is unaccountably lively after pain in head, which comes on generally about 6 P. M. The forehead is very hot then. Before this she had materially improved. She was treated till Dec. 22d with ferri et quin. citras, and im- proved very much, so that she was not like the same child. The fits had ceased for some time before she quitted the hospital. No. 52.— W. S., set. 49, m., ad. Feb. 24th. Ill ten weeks with catarrh and fits. He was suddenly seized with unconsciousness while at his work (bootmaking), and remained so for half an hour. Did not struggle, or bite 148 EPILEPSY. his tongue ; foamed at the mouth. During the fit his mouth was drawn to one side. Has only had two fits; the first came on nine, the last three weeks ago. He had one fit previously seventeen or eighteen years ago. When he talks his mouth is drawn to one side, and his tongue to the oppo- site. He was ordered carbonate of iron and tr. nucis vom. with bark, and subsequently ammonia. During five weeks that he remained under observa- tion he had no return of the fit, and became much less nervous. He had one bout of sharp abdominal pain (neuralgia). No. 53. — M. B., set. 19, f. Ill four or five months. After having had a sore on her finger became low and weak, and then fits came on. Last week she had fits every day but one ; she is much convulsed in them j they continue as a succession three-quarters of an hour. Screams in the fits, has sopor after. Complains of a lump in throat, and is very nervous. Skin cool; pulse natural; catam. regular; bowels regular; head very hot. During the six months that she remained under my care this heat of head was a constant and remarkable symptom ; it was attended with very marked activity of the circulation in the head, contrasting strongly with an opposite condition in the hands and feet. The forehead presented a uniform red flush, scarcely obliterated for an instant by pressure, while in the hands the blood after being pressed out returned again very tardily. At times she had much "swimming in the head, feeling as if she should fall when she got up," and much headache in forehead and temples. The distress of the head was relieved by leeches to the temples, blisters to the neck, ice locally applied, and dry cupping. She was better during cold frosty weather. The fits occurred at various times of the day, not at night. Her speech was lost on some occasions for two hours. Debility was marked. Except that she gained strength, and that the fits were not so frequent or so strong as they were at first, not much was accomplished. She took quinine, iron, strychnia with some advantage, large doses of assafoetida seemed also beneficial, and small doses of morphia and henbane. Hydrocyanic acid was of no avail. This case was certainly not mere hysteria; the state of the circulation in the head was distinctly abnormal, and assuming the intracranial to be simi- lar it would account for most of the symptoms. There was no real plethora, the primary and essential defect was loss of tone in the cranial vessels and nerves, a permanent sympathetic paresis. No. 54. — A. W., aet. 32, f., ad. July 6th. HI five weeks, has had one fit each Friday. In each fit the two inner fingers begin pinching and shooting, and twitch ; the pricking, &c., extends up the right arm to the side of the head, " the arm works," and then she loses all consciousness ; she falls down, her face is drawn to one side, she is convulsed and bites her tongue (seen). The feeling in the head sometimes occurs without a fit. Is always drowsy. Does not sleep well. Suckling five months. Has had eight children, some born dead, only two living. None of them have had eruption. Not anaemic. Very nervous and excitable. Dyspepsia lately. Bowels irregular, open much at times. She only remained seventeen days under observation in which time no improvement took place. She took iron, ammonia, and hen- bane. No. 55. — E. F., f., aet. 15 months, seen April 25th. Ill nine months, first had severe diarrhoea which was followed by slight convulsions, and then by bad fits, which have continued ever since, occurring generally every week. Sometimes the fits occur on a Saturday morning, at 8 A. M. for several weeks together, though there may be fits also in the intervening days. The most EPILEPSY. 149 remarkable phenomena as I see her at present are the great collapse of the ribs in inspiration, the prolonged groaning character of the inspiration, a certain amount of cough and attempt at expectoration. She swallows well. Consciousness is impaired since her illness, but not lost; there is no evident paralysis. Urine appears natural, but very scanty. Pupils of medium size. No fit now for eight days, the fits last about five minutes, but it is half an hour sometimes before she is quite restored. She has been breathing as at present for ten or eleven days. Crams very much her fingers into her mouth, no trace of teeth, is fed from a bottle. Death occurred a few days after ; a careful autopsy discovered nothing morbid in the brain, nor in the organs of the chest and abdomen. No. 56. — S. S., 83t. 45, m., ad. December 22d. Ill about four weeks, since a fall from a height of about eight feet. Is of stout, rather short make and sanguineous aspect. He had been cupped at the back of the neck ad oviij, had a seton put in the left arm, tartar emetic ointment applied to the neck, and had been purged without benefit. He suffered from attacks of the following kind occurring five or six times a day. He begins to wink, and then both eyes become drawn quite under the lids towards the right, one inwards and the other outwards ; he then loses consciousness for four or five minutes, and falls down, does not scream, but moans as if choked. I witnessed the attacks more than once; they were perfectly involuntary, not attended by much flushing of head. He feels tremulous and nervous ; does not sleep well ; has a trembling in the head when he lies down. Not an in- temperate man. No syphilis. Bowels open. Pulse of good force, skin warm. "Was similarly affected two years ago, and got well after six months. He remained under observation till Feb. 20th, when he ceased to attend, having had only slight attacks in the previous fifteen days, and having been nearly free during several former weeks. Assafoetida in gr. x doses '2dis Jioris, and iron and quinine seemed to be the efficient means in subduing the neurosis. No. 57. — A., aet. 39, m., has had a touch of African fever formerly. Ad. April 2d. Ill three or four months, on and off. At first he lost his speech, it is now impaired. His arms and legs feel weak at various times, chiefly on exertion. Has a dull pain across the forehead, not constant, and not worse when lying down. Head rather warm ; no tenderness in cranium or spine ; intellect seems obscured, memory impaired ; skin cool, pulse weak, pupils sluggish, left larger than right. Subsequently he had trembling of the right arm and leg. Two blisters to the neck. Pot. iod. et hydr. bichl. produced improvement; he ceased attendance, having, as he afterwards stated got quite well. He was readmitted Feb. 23d of the following year, having then been ill a week. His condition was sufficiently obscure, he appeared to be in a state of general excitement and fussiness. His knees and right arm tremble. Sometimes he falls down, sometimes loses consciousness. He is pallid, free from fever, head rather hot, urine not albuminous. I gave him ammonia and arsenic with which he improved a good deal, his right arm became steady, his speech improved, no loss of consciousness occurred, but he had on two occasions some appearance of rheumatism in the right knee. Just after this in the night at 10 P. M. he suddenly lost his speech, and remained speechless till his admission into the ward March 31st (two days later). The day after he had a fit, consisting of convulsive movements of all the body, but chiefly of the right side, with rigidity of the flexors of the arm and ex- tensors of the knee. April 5th. There is complete paralysis of motion and sensation in the right arm and leg, which are relaxed. Mouth is drawn to the left. Reflex movements could be excited in the paralyzed leg. The 150 EPILEPSY. fits above mentioned recurred frequently during his stay in the hospital, the intellect remaining clear. They lasted two or three minutes, several occurring one after the other ; they were not succeeded by coma ; he was able to recognize his children immediately after them. No fits occurred for about twenty-four hours before death, which took place April 10 ; but he became very weak, unable to swallow, and gradually sank, his intellect re- maining clear to the last. His evacuations were all passed under him. At the P. M. the cerebral veins and sinuses were found full of dark blood, the smaller veins were filled, but the gray matter was not dark, nor the minute vessels injected. Considerable subarachnoid effusion existed, and there were some patches of opacity over both hemispheres. The substance of the brain was firm and consistent, the white matter congested. In each lateral ven- tricle there were 5vj of serous fluid, and the vessels on the walls were con- gested. Nothing morbid at all was found in the brain or cerebellum, though they were very carefully examined for two hours; nor was there anything morbid in the spinal cord. Microscopic examination detected nothing in the brain. The thoracic and abdominal viscera were fairly healthy. No. 58.— E. C, f , set. 28, mar., no children, ad. March 28th, 1861. Has been ailing since she had inflammation of lungs and liver three and a quarter years ago. Three months ago was first attacked with giddiness, and just three weeks after an epileptic fit occurred. After this (the first) they returned at the rate of four or five a day, and now occur three or four times a week. When the attack comes on she turns pale and giddy, feels as if a blow was given her on the head, falls down, loses consciousness, and becomes very sick five or ten minutes after. She has constant giddiness, is very anaemic. No tenderness about head. No worms. P. 132. Catam. regular, but excessive. Her health is better during the summer. Her mother may have had fits, but a brother and a sister are quite free. Pupils equal. In January, 1863, she stated that her head always felt hot, and was benefited by cold applications ; when she becomes giddy her head is dreadfully hot. The recumbent posture relieves her head generally, it aches less; when erect it feels weary as if she needed to rest it against something. She feels weak and weary, and looks languid. March, 1864. During the last five months she has become the subject of very marked proptosis, the globes are not nearly covei'ed by the lids, they feel tense, and (especially the right) are notably injected; the lids are also very red. The vision is pretty perfect; she can read for a short time, but afterwards the letters become confused. There is great fulness and bulging of the upper eyelids, and great pain in, and above and behind the globes. This pain is much aggravated at night, and destroys her sleep. There is also very forcible pulsation of both carotids, when one of them is compressed the pain in the eye is somewhat relieved. No thyroid enlargement. No palpitation. Ice applied to the eye and to the neck gives more relief than anything else, but it is only temporary ; she goes to sleep, but is soon aroused by the pain. The radial pulse is very weak and rapid, varies (sitting) from 120 to 140. The pupils are very small. The fits have become much less frecjuent. In the summer of 1862 she had a period of 110 days with only one slight attack, and in 1863 she remained exempt from June 16th to December 23d (189 days). Since then she has had two or three attacks. The remedies which have done most good have been tan- nin gr.

M., had none since his first, five years before. He went into the fit with a loud' cry, fell down, and bit his tongue. Does not know how long he was in the fit, but was told by his friends that he had another at 4 A. M. this morning. The attacks occur during sleep, without any previous intima- tion. Not at all anEemie. Is a teetotaller. No worms. Syphilis denied. Does not suffer from pain in head. Pulse steady. No epilepsy in his family. Is out for many hours cab-driving. He took pot. iod. + ammon. carb. with benefit, but attended only about a month. Among the above 25 cases there are 16 males and 9 females, and among sixteen other cases I have notes of, there are 7 males and 9 females. In the total number, therefore, the males are to the females in the proportion of 23 to 18. The oldest patient was a male, set. 64, the youngest a female set. 15 months. There are 10 under the age of 20 years, and only five above that of 40. The attacks were non-convulsive in three instances ; No. 47 was a marked example of " le petit mal." Injuries to the head were the assigned cause of the fits in Nos. 40 and 49. In almost all the remaining cases the cause was quite obscure. General hypergesthesia and nervousness "was marked in Nos. 41, 43, 46, 53, and 54, but in quite as many or more instances there was no trace of it. The fits were few and far be- tween in Nos. 49, 52, and 59. There were other indications of ner- vous disorder in Nos. 39, 40, 42, 43, 46, 51, 52, 57, 58, Hyperaemia of the head was a notable symptom in Nos. 38, 43, 53, 58. Debility was evident in Nos. 41, 43, 46, 51, 53, 54, 55, 58. There were premonitory symptoms in Nos. 35, 38, 43, 44, 51, 54. In 54 there was a regular aura commencing in the hand, in the other cases there were various sensations in the head. Pain in the head was com- plained of to a notable extent in Nos, 46, 51, Giddiness was a marked symptom in Nos. 45, 49, 53, 58. In 52 there -^as some amount of facial paralysis after the fit. In Nos, 35 and 41 strychnia appeared to have a good effect. In 53 and 56 large doses of assa- foetida appeared useful. In No. 36 alisma plantago was perhaps curative, but in 37 it quite failed. In Nos, 38, 39, 40, 42, 58 bella- donna or henbane seemed decidedly beneficial, though as they were mostly given with other drugs it is difficult to tell how much of the result was due to their action alone. The remedies with which they were usually associated were zinc, tannin, and ol. morrh. In Nos, 45, 51, 52, 5Q tonic treatment, ammonia, iron, and quinine seemed to be really curative. The nocturnal restlessness and quasi ' The sequel of this case has been very sad, but instructive. After the prop- tosis and congestion of the oi'bital tissues and lids had existed nearly six months the pain became greatly exaggerated, the conjunctiva in both eyes greatly chemosed with fibrinous exudation, and effusion of lymph took place into both anterior chambers. Prolonged hypergemia has thus issued in destructive inflammation. 152 EPILEPSY. delirium, and the previous neuralgia incline me to tliink that No. 51 was au fond a case of malarioid remittent. No. 59 is a case of great interest. The patient is a calm, sensible, uncomplaining sufferer, tractable and reliable, and regular in her attendance. The improvement in her state has been so marked that I am hopeful she will ultimately be quite restored. The recent development of prop- tosis with great vascular congestion in and around the globes and strongly-marked pulsation of the carotids is highly suggestive, espe- cially when the absence of thyroid enlargement is taken into account. It is difficult not to regard the proptosis, &c. as a part of the origi- nal nerve disorder, a variation probably of its seat. The head had previously been very hot, when giddiness came on, indicating that an increased flow of blood to some part of the encephalon ensued at such times. Latterly the branches of the ophthalmic artery seem to have been unduly relaxed and to have given rise to the orbital hypersemia. The carotids are in the same state. The fact that there is no thyroid enlargement seems to prove that the smaller arterial ramifications are the main controllers of blood-supply. As long as they retain their due tone and consequent calibre no exces- sive flow of blood to a part will ensue, though the main trunks may be throbbing violently for lack of tonicity in their coats, or from paresis of their regulating nerves. When, however, the small arteries, and ultimate ramifications of the sympathetic are thus affected the tissues which they supply have their vital actions increased, and we then get various phenomena according to the normal function, origi- nal excitability, and tendency of the organs concerned. It is very curious thus to find an excess of vital manifestations essentially de- pending upon a failure of vital power (vis nervosa). It is most probable I think that in the earlier period of this case increased blood-flow took place towards the medulla oblongata and mesocephale. It is very evident how important it must be to distinguish cases where the cerebral excitability is primary, and where the hypersemia if any occur is consequent on this excitability, and those where as in the above instance the pathological order is reversed. In those instances where long intervals of apparently perfect health intervene between the fits there does not seem to be any indi- cation for the administration of drugs. The diet and mode of life should be however duly regulated, the object kept in view being to increase power and diminish excitability. In the two fatal cases which occurred the autopsy manifested no cause for the disorder. The general conclusion which I am led to adopt from the above review of my cases is that epilepsy in its nature is a disorder of the nervous centres quite analogous to neu- ralgia and hypersesthesia of the nerves. Some cases approximate to the former, but the majority to the latter condition, and in some the morbid action is maintained and aggravated by hypersemia, either depending on arterial relaxation, or on local attraction of blood. The disease which it most resembles is, I think, scrofulous ophthalmia. HEADACHE. .153 CHAPTER XIV. HEADACHE. Headache is a symptom present in so many and different condi- tions that it has no claim to be considered a distinct disease. The article upon the subject in Dr. Copland's Dictionary treats of the various kinds in a very exhaustive manner. I shall only enumerate the various kinds of inorganic headache that are met with, and give some illustrations of them. One of the commonest kinds is that •which coexists with prostration of nervous power, in which I conceive the state of the brain much resembles that of a nerve suffering from neuralgia of debility. A second is hypersesthetic headache, where, along with more or less debility, there is considerable excitement and hyperacute sensibility to all impressions. The two forms are certainly distinct, though transitional instances are more frequent than typical. The means which relieve the former are apt to aggravate marked cases of the latter. A third form of headache is the result of active hypersemia, and is characterized by fulness of the vessels, heat of head, by being aggravated (this is not invariable) by the recumbent posture, and by the relief afforded by cold applica- tions, purgation, and depletion. A fourth form is sympathetic, depending on disorder of the stomach or of some other organ. Dr. Sieveking describes a haemorrhoidal form of headache, sudden, violent, and vertiginous, attended with impaired vision and irrita- bility of temper, and probably dependent on rectal irritation, (V. 3Ied. Times and G-az., Aug. 12, 26, 1854.) In all these I consider the encephalon itself to be directly affected. In hemicrania and other forms of neuralgic headache the nerves of the scalp suffer. In rheumatic headache the same occurs in some instances, in others the nerves of the dura mater are implicated in the morbid action. Gouty headache may present various grades of irritative or inflam- matory phenomena corresponding closely with the neuralgic or inflammatory results of the action of the materies morbi in other parts. In many cases there will be indications of the existence of the gouty diathesis, but it is very important to be aware that, as Dr. Copland states, it may be the first manifestation of the disorder. Trousseau relates an interesting example of hemicrania replaced by gout, and states that the articular and the neuralgic affection often alternate in the same individual, and that the latter may be the sole manifestation of the diathesis in the offspring of gouty parents. Rheumatic and neuralgic headaches are often very difficult to distinguish except by testing them with remedies. Pot. iodidum or 154 HEADACHE. guaiacum is usually curative of the one as tonics are of the other. The urine is more often lateritious in the rheumatic than the neuralgic disorder, and there is less debility. In gouty affections we shall generally find a deficiency of uric acid in the urine if the total amount passed in twenty-four hours be estimated. Syphilis not unfrequently occasions headache, or rather pain in the head, of varying degrees of severity, often much resembling the results of rheumatism. It is generally amenable to full doses of iodide, but may require mercury. No. 60.— Mrs. F. S., set. 38 (?), seen July 27th, 1861. Has been much in India, but never had fever or ague. Has no mental distress. Looks thin, wan, and poorly ; forehead large, peculiar expression of countenance giving one the idea of impending insanity. Has suffered for three or four years with headache paroxysmal, but very severe indeed while it lasts, which is from twelve to forty-eight hours. It returns once or twice a week, is relieved by nothing but chloroform (inhaled) and morphia; the latter acts slowly, she takes 2 grains without any sopor ensuing; chloroform relieves immediately. At the time when the headache is present is almost distracted by violent throbbing at the vertex, which is somewhat relieved by firm pres- sure. Head then seems hot to her, it is cool now. She can lay her head down without increasing the pain. Superficial veins of neck very large. Does not sleep well always, has sometimes restless nights preceding the attacks of headache. Some decayed teeth, but they cauise no notable un- easiness. No worms. Urine palish, free, acid, sp. gr. 1011. P. soft, weak. Skin cool. She was ordered strychnia with citrate of iron and quinine ter die, and to take supper with malt liquor at night. In about six or seven weeks she had benefited very much, slept better, but still had to take a cup of cocoa in the course of the night. At this time she had hemicrania of the right side, which she said was quite different from the head-attacks she had had previously. The veins of the neck did not appear full now. A month later she suffered pain extending down the right leg from the hip to the toes, apparently in the centre of the limb, quieted by cold, and induced by heat. Nov. 8th'. Pain has shifted from leg to arm, the right shoulder and arm are stiff and painful each morning, the pain runs down the arm. " It is a misery to turn or move in bed." During the day the pain subsides. Headaches less and less. This arm-pain was soon cured by chloroform lini- ment and the Turkish bath. Jan. 6th, 1862. The headache has recurred the last three weeks with hysterical symptoms and depression. It is most probable that the neuralgia in this case was of malarious origin, although there was no history of fever. The tonic treatment plainly averted to a great extent its recurrence. The disorder exhibited the usual shifting tendency of neuroses, its hemicranial manifestation, and the quasi-rheumatic affection of the limbs was less-distressing than the original in which the brain itself seemed to suffer. No. 61. — Mrs. W., set. 24, has been much in India during her early life, and has been under my care previously for neuralgia of the side, and for ery- thematous flushing of the face.

Ill three months, head feels light, and sore and weak, occasionally has sharp darting pains in it, which make her stagger. Can't sleep at night for tenderness of head. Some deafness. With iron, calumba, and cod-liver oil, and henbane at night, all her symptoms very much improved. No. 64.— H. P., ^t. 10, m., ad. Feb. 6th. Never well from birth. Has frontal headache almost every day, eyes feel as if on fire. Suffers with violent attacks of sickness, retches much. " Eyes work continually." Has occasionally swelling of the dorsum of the left foot. Ague has occurred in the village where he lives. Is languid. With citrate of iron and quinine + tr. nucis vom. he got a great deal better; after an accidental relapse (per- haps from some wrong medicine being given) pot. iod. was added to the tonic and ol. morrh. given, which he continued till June 10th, when he was fairly well except being still rather weak. In the first of these four cases there was extreme neuralgic suffering, in the second there was much of this and also of hyperaesthesia, in the third the brain seems to have been in a condition re- sembling that of " anaesthesia dolorosa" in a nerve ; the last affords an exam- ple of cerebral debility and neuralgia, with associated stomach disturbance. That mere exhaustion of the brain will cause gastric disorder I am satisfied.

In a week she slept better, appetite was better, the pulse had fallen to 72, and was of good volume.

Is iu a state of 156 HEADACHE. the most extreme hyperaestbesia, crying and agitated, can't sleep, walks about the room all night long. No appetite. Urine scanty and thick. Says her illness commenced with rheumatic pains in left arm extending up to shoulder, these have been gradually leaving her, and the arm, which was very weak so that she could not hold a teacup, has become much stronger. Her head and nerves became aflFected three or four days after the rheuma- tism came on. June 4th. She was discharged very much improved, had been mending steadily since March 16th. She was treated at first with aperients and antispasmodics and with material benefit, but after the relapse March 12th she took calomel and colchicum at night, daily ad vices iv., then aJt. noct. for a week, then twice a week for more than a month. Black draught was given almost daily for nearly the same time. The hyperaestbe- sia and nervous distress in this case were very great, quite verging on in- sanity, and proving that the cei-ebrum was essentially involved in the morbid action. There was no indication of gout. 1 doubt whether mere purging was the efficient remedy as she had taken aperients pretty freely before her relapse, including at last nightly doses of ol.

He took at first ferri et quin. citrat. gr. vj -f pot. iod. gr. iij ter die, and a small opiate at night for three weeks, subsequently tr. nucis vomicae was substituted for the pot. iod. He ceased attendance March 2d, but I heard of him on April 18th that he continued much better, more submissive and controllable, and attended school both Sunday and weekday, which he had not been able to do previ- ously. In all these three cases there was very marked cerebral hyperassthe- sia and excitement with more or less pain in the head. In the first the condition was of asthenic character, purgatives were of marked benefit and stimulants unavailing. In the two latter tonics and sedatives were of marked remedial efficacy. It is most probable in the first case that the dis- order was induced by some morbid condition of the " primae viae," while in the others it seems to have been based chiefly on debility. It may depend very much whether the morbid action affect the nerve-cells or the white fibres which result is produced, viz., mental excitement or pain. Pain we know is caused by an enfeebled condition of nqrves, and delirium we also know results from cerebral exhaustion. The phenomena vary with the tissue affected. No. 69. — E. A., f., ast. 32, ad.

Sj (efi'erv.) tei' die. This soon stopped the sickness, and then tannin pills were given bis die in addition. By Oct. 16th she was very much better, the stomach was right ; she had had two returns of the numbness but much less than it used to be. In this case the gastric disorder was primary and the head-pain and cerebral paresis were produced as I believe by an inhibitory action exerted through the sensory nerves of the stomach on the higher nervous centres. Various morbid conditions of the primx vise will give rise in predisposed persons to headache. Dr. Prout^ describes excessive acidity of the caecum as producing in certain persons severe frontal headache, attended with complete intolerance of light and sounds and a state of mind bordering on delirium. After a longer or shorter duration the pain ceases, sometimes quite suddenly; and this sudden termination Prout connects with a relaxation of a spasm of the bile-duct, and a flow of bile into the intestines, partly from a description of the sensations which others have invariably experienced, and partly from his personal experience of the disorder. CHAPTER Xy. VERTIGO. This symptom, for it scarcely attains the rank of an independent disorder, is of suflGcient interest and importance to require a brief notice. Its relation to epilepsy is recognized in the term epileptic vertigo, which is applied to the lesser form of the malady. It is eminently a dynamical disorder, as though often occasioned by toxic agents its most exquisite forms are certainly generated by influences of a totally different kind. It occurs ,as Dr. Copland justly observes in predisposed persons both from excess and from deficiency of blood supply to the brain. It is also produced by various causes of cere- bral debility without any notable variation of the circulation. Any sudden diminution of the pressure exerted upon the encephalon by the blood circulating through it and by the subarachnoid liquid seems to induce giddiness. As regards the blood the effect of im- pending syncope is familiar. As regards the subarachnoid fluid we may cite Cruveilhier's experiment. He states that if the sheath of the dura mater in a dog is punctured between the atlas and the occipital bone, and the spinal fluid allowed to escape, the animal reels about like a drunken man, and lies down for hours in a state ' "Stomach and Renal Dis.," p. 81. 158 VERTIGO. of stupor. The day following he is quite recovered. Probably the giddiness which we experience on rising quickly, after having been stooping down for some time, depends in great measure on the reflux of the subarachnoid fluid towards the spinal cavity, which while the the head was depressed gravitated towards the cranial. It is worth observing that the giddiness does not occur while the pressure is increasing, but when it ceases. The vertigo which is felt after rapidly turning round, or in states of nervous debility from any quick movement of the head, cannot I think be owing to any change in the circulation or in the external pressure, but to a dynamic derangement of the cerebral structure. It is induced the more readily in proportion to the weakness of the nerve-power. Its nature is somewhat elucidated by the fact that the same feeling is experienced on looking down from a great height, when we have not a distinct perception of the objects below, or when we look at a rapidly-flowing stream when wading across -it. Mayo says "we lean upon our eyesight as upon crutches," and if we cannot lean securely, we become giddy. I shall cite a few cases in which giddiness was the prominent symptom, partly for the sake of illustration of the subject, partly for their bearing on other affections. No. 70. — T. C, set. 55, admitted Feb. 5t.h. Of large make, face red. Ill four or five moDths with constant giddiness, which is better when he lies down, and after meals, except breakfast. Has had some rheumatism, but no gout. Otherwise quite -healthy. P. excited and soft. Marked pulsation of the abdominal aorta. Sleeps very well. He remained under my care six months, and during almost all that time there was marked hyperaemia and heat of head, his hands and feet being cold. He was not at all hyper- Eesthetic. I exhausted all my skill to relieve his giddiness, but in vain. Pot. iod., antimony, colchicum, mercury to mild salivation, purging, alkalies, strychnia, and other tonics failed to eifect any material improvement. Bel- ladonna (gr. ^ of the extract ter die) made his throat dry, but availed nothing to lessen the hyperaemia and giddiness. A seton in the neck was the only measure that accomplished this for a time, but soon it also failed to benefit. The noteworthy points in the case are the connection of giddiness with hyper- semia of the head, the absence of any epileptoid affection, and the relief to the giddiness notwithstanding the hyperaemia in the recumbent position. The latter circumstance is to be explained by assuming that the effect of gravitation is more than counteracted by the slower action of the heart, and the greater steadiness of the head. The absence of morbid excitability in the encephalic centres was probably the element wanting to give this case the epileptoid character. This the hyperaemia did not generate. No. 71. — E. M., aet. 63, admitted Feb. 9th, ill three months. Had smart epistaxis at first. P. now of fair force. Complains of great weakness, has not strength at times to speak. Her eyesight fails now and then, she turns giddy and falls. Much sense of pressure at vertex. Is obliged to lie with her head high. With strychnia and ol. morrh. continued for some length of time she got well. This case was clearly one of cerebral debility, yet the rejumbent position was not beneficial. VERTIGO. 159 No. 72.— W. C, m., set. 54, admitted June'22d. Ill three weeks. A short, strong, thick-set man. Was attacked with giddiness suddenly, when walking about is giddy, feels as if he should pitch downj forehead hot, eyes dull, is better on lying down. Skin cool. P. soft. B.open. Urine very clear, pale. T. clean. He had strychnia increased from gr. j\ to gr. ^^ ter die, blis- ters to the neck and aperients, and quite recovered in two months. The tonic was certainly the efficient remedy, the others were employed rather to guard it, on account of the peculiar robust appearance of the patient. In both the latter instances I think the marked effect of the strychnia shows that the pathological state was one of cerebral debility, more than of anaemia general or local. In the latter case there was none certainly, and it was not marked in the former. No. 73. — C. C, set. 12, admitted Dec. 11. Ill since about June, when he was struck on the back of the head with a cricket-bat, and since then has suffered from dizziness and violent headache, not constantly, but at various times, and especially if he exerts himself When he is ill in this way he has repeated vomiting. The attacks last one to two days. No tenderness of head. Pupils large, active. P. weak. Skin cool. Sleeps well. He took citrate of iron and quinine with tr. of nux vomica with great benefit. This case is certainly interesting as showing how the dynamical disorder remaining after a concussion may be aggravated by expenditure of the nerve- force, and removed by invigorating treatment. Among the debilitating causes which produce giddiness none is more efficient than influenza. It is very remarkable how suddenly and severely the cerebral affection supervenes, and how long it con- tinues. In the case recorded at p. 75, it was weeks before the patient could move his head as usual without feeling dizzy. In the following case the cause is not so clear, but I think it very likely that the total abstinence may have predisposed to the attack. No. 74. — E. W., get. 48, conductor, admitted Sept. 15th. Ill four days with giddiness and headache, could hardly stand this morning. Has not the least pain in head, but it feels light, he can scarcely see anything. Is not anaemic. Says he is a strong man, never ailed with his head till a month ago. Left off taking alcoholic liquor three months ago. Never drank to excess. With strychnia he improved very much. In a case of nearly complete paralysis of both legs and the right arm from exposure to cold and wet, giddiness was at first a very marked symptom, and continued for more than a month. Tonics effected a cure. Venereal excess is often a cause of vertigo, as it is of epilepsy. A case was recently under my care in which irritable dyspepsia, general hypersesthesia, and giddiness were very marked, and had evidently originated from this cause. He was greatly benefited by nitrate of silver, creasote and opium, and subsequently by quinine and arnica. The tendency to relapse on leaving off the quinine was evident. Even when his digestion was fairly good, he experienced some days giddiness and confusion in the head with a sense of dulness and temporary double vision. Moving his head quickly would bring on these symptoms. There is a form of giddi- ness which occurs in old persons, the nature of which is very obscure, 160 CHOREA. It appears as a single symptom unassociated with any special state that can account for it. It occurs paroxysmallj, and is sometimes quite absent. I will not affirm that it is peculiar to the aged, but I have not met with it in others. The practical point to be aware of is that such giddiness is often curable by hydr. bichlorid., given alone or with tr. cinch. Rheumatism and syphilis affecting the brain or its membranes may cause giddiness, but, according to my expe- rience pain is a much more marked symptom in such states. In numerous instances of renal degeneration that I have met with gid- diness has been but rarely complained of. Organic disease of the head is of course often attended with giddiness, but it is seldom, I think, a very prominent symptom, and the nature of the case is evi- denced by other and graver phenomena. CHAPTER XVI. CHOREA. Chorea is a disorder of great interest to the student of nervous affections, inasmuch as its very various and curious phenomena are not only capable of being explained to a considerable extent by established principles, but also when duly considered afford valuable aid to the inquirer into the nature of analogous forms of morbid action. It is unnecessary for me to give any detailed ac- count of this well-known disorder. I shall only allude to the facts of its being sometimes confined to the muscles of one side ; of the irregular muscular action being sometimes replaced in a great degree by paralysis, the affection then bearing a notable resemblance to imperfect hemiplegia ; of the frequent impairment and enfeebling of the memory, temper, and intellect ; and of the occasional dependence of the phenomena on some peripheral irritation, such as is occasioned by pregnancy, dentition, constipation, &c. Some comments on these facts may be of value. Taking the onesided form of the disorder we remark that it seems to afford a proof that the encephalon is the part essentially involved. Unless this were so it would be very dif- ficult to conceive how the affection should be limited to one-half the body, which if this be admitted is quite intelligible. The same in- ference is supported also by the frequent impairment of the mental faculties, the cessation of the movements during sleep, and by the circumstance mentioned by Dr. Watson, that he has known it in several instances to be attended by pain of the head on that side only which was opposite to the agitated limbs ; the disease also being speedily cured by local detraction of blood from the painful part. The enfeebling of the mental faculties, the hemiplegic form CHOREA. 161 of the disorder, the promoting causes, and the usual "juvantia" clearly indicate that the disease is essentially one of debility. This debility is evidently not mere common general weakness, which is met with every day without any choreic features, but especially be- falls the nervous system. Chorea is thus most correctly regarded as a paretic affection of the brain and cord ; but, owing to the great tendency of weak nervous tissue to irritability, the phenomena par- take as much or more of undue mobility or convulsion, as of paralysis. We have here one of the most complete exemplifications of the often- mentioned law, that irritability and mobility rise as power fails. The production of the disorder by peripheral irritation appears to me to afford an interesting instance of inhibitory action, the morbid impression impairing the functional power of the nervous centres, and thus inducing a secondary paresis. This is certainly the case when chorea is produced by intestinal accumulations, dentition, &c., but in some instances, among which perhaps those where pregnancy is concerned should be included, the morbid impression made upon the encephalon is of a more directly irritating character. Romberg describes the chorea of pregnant females as almost always bilateral, the muscles of the face and tongue being invariably affected.' " The intensity of the movements is very marked, and they are often com- plicated with convulsions of an epileptic character. Many complain of a sense of numbness in the affected parts. The brain is almost invariably affected, and this is shown by headache, vertigo, a wild expression of the features, rolling eyes, unconnected speech, loss of memory, and great irritability." The signs of paresis and of ex- citement are here evidently blended together. In connection with the production of chorea by peripheral irritation may be mentioned its repression and cure by sulphuret of potassium baths, which must act by stimulation of the cutaneous nerves, and rousing of the ner- vous centres to a more healthy action. Beneke believes that it is in this way that all baths produce their general effects [v. Schmidt's JaJirb., vol. cxv. p. 101). The result of a well- devised tonic treatment in ordinary chorea is so satisfactory that no question can exist as to the functional nature of the disorder, and that it depends upon a failure of vital power, and not at least in the great majority of cases on any morbid matter circulating in the blood. It may stand as the type of a great class of diseases, in which a primary alteration of the vital endowment, a failure or perversion of functional power is the essen- tial circumstance. As, however, most diseases may arise from dif- ferent causes, so it may fully be admitted is the case with chorea. This, as we shall presently see, the test of remedies proves. When the malady appears to be a simple paresis, a steady use of tonic treatment is clearly the course to pursue. In most cases I find citrate of iron and quinine with liq. pot. arsenitis to act very effect- ually. Cod-liver oil I almost always administer at the same time in small doses. In some instances strychnia is preferable ; it has 162 CHOREA. been hi'glily praised by Trousseau, and I have had some experience myself of its utility. He recommended it to be given in doses suffi- cient to produce its physiological effects. This I have not found necessary, but it might be so perhaps in cases of great severity. The use of the interrupted galvanic current is of great service in many cases of chorea, and probably might generally be used with benefit. The two latter therapeutic results increase still further the rapprochement between chorea and functional paralysis. Cold bathing judiciously managed is probably second to no remedy in its calming and invigorating action on the nervous system. This means should be employed whenever it is practicable. With regard to cases where the disease is of such severity as seriously to threaten life by exhaustion, sedatives must be had recourse to. In a very bad case, detailed by Dr. Graves, morphia with arsenic proved less serviceable than stramonium with quinine, but recovery seems to be chiefly attributable to the persevering use of tepid salt water shower or douche baths three times a day. Purgation is sometimes of marked advantage. Dr. Prichard states that he saw a boy who had nearly the aspect of an idiot after a long- continued and severe chorea restored by a course of purgative medi- cines. Dr. Hamilton's cases prove that purgation may be curative even when the general state seems to contra-indicate it. A boy under his care, get. 8, was emaciated and exceedingly puny, and his abdomen lank ; but he recovered after having had during ten days a "most wonderful" discharge of feces nearly equalling in weight (i)s H. estimates it) that of his whole body. It is very mark-worthy that the appearance of the feces is sometimes healthy at first, then becomes unnatural, "black and fetid," and subsequently healthy again. So that in a case proving refractory to other means it would be desirable to continue steadily the administration of purgatives for some time. The best drugs would probably be podophyllin and aloes, combined with extract bellad. Or aloes with a little blue pill might be given with extr. nucis vomicae. The beneficial action of purga- tives may be explained either in accordance with the inhibitory theory of the disease, or on the supposition that they remove a materies morbi from the blood. Both views may be true in different instan- ces. The great majority of my choreic patients have had no indica- tions of any liability to rheumatism. Of fifteen cases, I find only one in which there was any valvular cardiac affection, and this patient is reported never to have had rheumatism or anything like it. On the other hand, rheumatic affections, though abundantly common, rarely show any tendency to choreic complication. It is quite possible that, in some cases, the rheumatic diathesis, whether that mean a poison (lactic acid) in the blood or no, may be an effi- cient cause of chorea, just as in certain cases benefited by continued purgation we may assume the presence of some "materies morbi" in the circulation, but there is certainly no necessary or intimate connection between the two disorders. Dr. Kirke's view is that the CHOREA. 163 association is not between chorea and rheumatism, but between chorea and valvular disease of the heart, excited by rheumatism. (V. Med. Times and Gaz., June 20th, 27th, 1863.) He thinks the valvular disease produces the chorea. Believing as we do that one important factor of rheumatism is a paretic condition of the vaso-motor nerves, and that chorea is especially characterized by a similar state of the musculo-motor, there is certainly so far a degree of affinity between them. Just as in epilepsy, a certain predisposition being given, a fright or a worm in the bowels will set up the morbid process, so it may be that, the tendency to chorea existing, the exciting cause of rheumatism will evoke the malady. Other causes will act similarly. Thus M. Zambaco quotes two cases of chorea depending apparently upon constitutional syphilis, and ceasing under the emploj'ment of specific remedies. Increasing experience leads us to attribute a very main part in the causation, location, and shaping of disease to the previous conditions which dispose the general system, and the particular part to suffer from the subsequent morbific influence. The former are the more essen- tial, the latter may vary greatly, both in kind, and in degree. When the former are very potent any even a slight exciting cause will, as it were, explode the mine. When the reverse is the case, the ex- citing causes must be much stronger, and may often fail to take effect. Though I am rather digressing I cannot help observing how these views of the supreme efficacy of the predisposing causes go to establish the retributive character of very many disorders which are often imagined to be accidental. We go on a long time infringing some law of our being, unknowing the while that every act of disobedience has added to the cumulating force of those de- ranged vital qualities, which one day some slight cause will call into terrible activity. The transgression is straightway followed by the dark shadow of its punishment. Chorea is quite an instance in point; the permitted indulgence in enervating habits, the neglect to insure a robust vigorous frame slowly generate the feebleness and mobility of the nervous system, which is the essence of the dis- ease. Even though the transgression be rather the result of neces- sity than of indulgence, as too often occurs among the poor, or has been the act of a progenitor, the organic law is inexorable. Inflam- matory affections, softenings^ of the brain or cord, or hemorrhages^ can very rarely be regarded in any other light than as sequelae, or complications of chorea, and not as causative. Still Dr. Watson's important observation above quoted should be borne in mind, and the possibility of the disease being dependent on cranial or spinal meningitis is perhaps not to be denied. The analogy of epilepsy would afford some support to this view as we have already seen that exceptional cases of this disease do occur, in which free depletion is of marked advantage. In one instance under my care, chorea ' V. Stoffella, Schmidt's " Jahrb.," vol. cxiii. p. 160. * V. Fuller's case, " Lancet," May 17th, 1863. 164 CHOREA. appeared as a complication of psoriasis of long standing in a girl, jet. 12. Both chorea and eruption yielded to arsenic with the aid of an issue. Certain cases of chorea are beneficially treated by tartar emetic. My friend, Mr. Gay, has mentioned to me an instance which had been treated ineffectually with many remedies, but which recovered under small doses of this. Gillette' advises it to be given for suc- cessive periods of three days with intermissions of the same length. He administers it in increasing doses, so that on the sixth day of its use, the patient takes 9 grains. Vomiting, and we may presume prostration, is not desirable. It is probable that the cases where this medication succeeds are of a sthenic character, and are analo- gous to those of delirium in which the same remedy proves some- times so successful. Regulated gymnastic exercise is often very useful in this disease, even where it is very severe. For the first three or four days pas- sive exercise alone is employed, the trunk and limbs being rubbed and moved. For the next eight or ten the limbs are made to per- form regular movements, and after this the patients are able to go to the gymnasium, and pursue systematic exercises. Great improve- ment occurs during the first ten or twelve days of the gymnasium, then there is a check, and after this improvement proceeds steadily. Choreic grimaces and contortions may be treated on the same plan by making the patient perform regulated movements. The beneficial effect results no doubt from the improvement produced by the exer- cise in the functional power of the motor nervous apparatus. With regard to the curious nerve disorders occasionally met with, which have more or less resemblance to chorea, epilepsy, and hys- teria, as I know nothing of them from personal experience I shall only remark that they seem either to be connected with irregular menstruation, or to be produced by imitative sympathy, or by some morbid emotional excitement. Probably in most of these cases the liberal employment of cold affusion, both actually and metaphori- cally, would powerfully tend to arrest the morbid manifestations. Nothing we know promotes such proceedings more than sympathy and attention, and nothing is more decidedly repressive than " throwing cold water" upon the exhibition. Bricheteau^ gives an account of an epidemic of chorea in one of Monneret's wards. Eight females contracted the disorder from the spectacle of one who was severely affected in the course of five days, and more would probably have been attacked had not the contagious influence been arrested by isolating the patients. Constans' records the oc- currence of an epidemic of hysterical demonomania. The inhabi- tants of Morzines in Haute Savoie, amounting to about 2,000, live in a state of great poverty and bad hygiene. The epidemic lasted four « " Ann. de Therap.," 1859, p. 102. 2 "Gaz. des Hop.," No. xlvi., 1863. s " Med. Critic and Psycholog. J.," Jan. 1863. PARALYSIS AGITANS. 165 years and affected as many as 110 persons. They were termed possessed, were mostly celibates, chloro-anseraic, or scrofulous, and suffered from gastralgia or dysmenorrlioea. Everything gave occa- sion for a paroxysm, especially the expression of a doubt that they were possessed. The phenomena were partly hysterical, partly maniacal. The affected retained sufficient consciousness not to injure or expose themselves in the most disordered actions. The epidemic was arrested by removing the priest, and intimidating the people by the presence of soldiers. The influence of diseased morale is sufficiently apparent here. CHAPTER XVII. PARALYSIS AGITANS. It appears to me a question whether two distinct affections are not often comprehended under this name. For on the one hand it appears pretty certain that there is one form which is met with in old persons, is quite incurable, and is associated with if not depend- ent on organic wasting changes in _^the nervous centres ; while another form occurs in younger persons, is more curable, and there- fore is presumably not dependent on organic change. Stoffella^ relates the case of a man, set. 79, who had the affection five years before his death. At the autopsy he found traces of atrophy of the brain with secondary dropsy of the ventricles and of the cerebral membranes, and an apoplectic cyst as large as a pea in the right optic thalamus ; the pons Varolii and medulla oblongata were re- markably stiff, the arteries at the base calcareous, and the lateral columns of the cord, especially in the lumbar region, traversed by grayish opaque streaks, which as well as the indurations in the pons and medulla resulted from embryonal connective tissue. Cohn, who has recently published a paper founded on an experience of six cases, gives two autopsies,^ in one of which there was marked cere- bral atrophy, and in the other wasting of the cord opposite the second cervical vertebra. The ages of the patients, both males, were 49 and 74 years. The first had been employed in using mercury. Skoda^ details the autopsy of a female, 83t. 34, who had been affected about 2|- years, and died of variola. The brain was tough, the pia mater oedematous, the walls of the ventricles, the fornix, pons Varolii, medulla oblongata, and cord were remarkably stiff, both optic nerves were flattened and stiff. In some opaque reddish spots in the brain the nerve-tissue was destroyed by embry- 1 Schmidt's "Jahrb," vol. cxiii. p. 39. 2 Ibid., vol. cviii. p. 303. 3 Ibid., vol. cxix. p. 294. 166 PARALYSIS AGITANS. onal connective tissue, which occasioned also the induration of the pons and medulla. The muscles were very fatty, the neurilemma of the nerves of the upper limbs was thickened. The following histories may serve as examples of the more cura- ble forms of the disease. A male/ set. 57, came under Dr. R. Rey- nolds' care suffering with vertigo and general disturbance with paralytic tremor of the whole right upper limb, which in the situa- tion of the biceps was 4° F. hotter than the other. The sensibility was unaffected. After five applications of an 120-link Pulverma- cher's chain each lasting an hour the spontaneous jactitation com- pletely ceased. By continuing the same treatment every other day the power of the arm was almost quite restored in a month. The disease was recent, having commenced only fifteen days before he was submitted to treatment. Graves^ gives the case of a female, set. 25, who after a severe fright became vertiginous and hemiplegic and was laid up in bed three months. The hemiplegia gradually declined, but the muscular power remained weak, and very imper- fectly under voluntary control, most of the muscles being in a state of perpetual motion. Amaurosis also affected both eyes during the disease, but one recovered completely, the other very imperfectly. She could not walk slowly, and when she had commenced walking she could not stop without considerable difficulty. The following cases have come under my observation at St. Mary's, the two latter being under my own care. No. 75.— S. M., f., set. 12, ad. April .3d. Of healthy aspect. Ill three months with catarrh and cough, last three weeks has had vomiting which has got worse. She rejects everything which she takes shortly after swal- lowing it, but has no pain in the stomach. Slight epigastric tenderness. B. costive. T. whitish. Much thirst. P. 70. Appetite good. Her right arm is in continual vibration ever since her illness commenced. Lung and heart sounds healthy. 4th. I found her asleep to-day and her arm quiet. She had two purges of calomel and haust. sennse. On 6th she was electro- magnetized for about ten minutes, and in about one hour after the arm became quiet, and has remained so ever since, and the vomiting also has ceased. 13th. Discharged. No. 76. — J. K., labourer, aet. 60, ad. March 16th. A broad-made, strong-looking man, not anaemic. Had rheumatic fever seven years ago, not so well since. Thirty years ago he was frightened by a bull who tossed him into a hedge, and he has shook ever since. His hands and arms tremble, his hands shake so that I cannot feel his pulse. He has pretty good muscular power in his arms. He does not seem to have been intem- perate. He only attended a short time on account of some lumbar rheu- matism. No. 77. — J. H., set. 47, labourer, ad. Sept. 24th. Is a large man. Complains of tremor of the right upper extremity ; the muscles of this limb have full power, but quiver and twitch constantly except while he is quiet as in bed ; the pectoral muscles of that side are involved. There is some 1 Schmidt's " Jahrb.," vol. cxix. p. 294. 2 "Lancet," Dec. 3d, 1859. PARALYSIS AGITANS. 167 tremor of the legs, but nothing like that of the arms. Both however are decidedly weak ; the knees are sometimes very stiff. No numbness of the right arm, but has pins-and-needles sensations in hand sometimes. When the shaking stops he has aching in the right scapula, and along the biceps. No pain or tenderness in the spine. When first attacked his eyes were always " winking," not lately. Sight and hearing are quite good now, but his speech, memory and vision are occasionally impaired. The least excite- ment makes him worse. He sleeps, eats, and drinks well. Sweats very easily, much at night. Was affected in the same way two years ago, was under my care and soon got well, remained quite well for one year, then the disorder came on again at intervals ; some days he would have it and others not. I gave him at first strychnia, iron and ether, and faradized his arm. This treatment, especially the electricity, was rather injurious than otherwise. I changed it after eight days for tr. hyoscyami 3ss t^f d^^j under which he rapidly improved and ceased attendance in a fortnight. Petrseus^ relates two severe cases, observed in the Copenhagen Hospital, one of which proved fatal. Nothing was found at the autopsy but fatty degeneration of the heart, and pneumonic con- solidation of the right lung. He remarks on the tremor not being constant in many cases, ceasing for some days and then recurring with fresh force ; or changing its seat from one part to another. The tendency to steady increase is, he thinks, specially character- istic of the disease. All weakening influences whether of mind or body are apt to produce the disorder. Cohn distinguishes tremor from paralysis agitans. He considers the first as paretic debility and not as a spasm ; and derives it from failure of the tone of the voluntary muscles which they receive from the nervous system. The causes of spasm and of tremor are the same. Paralysis agitans he considers as tremor complicated with palsy, the latter involving even the muscles concerned in swallowing and the sphincters, and being attended with anesthesia. The paralysis generally super- venes at an advanced period of the disease and is usually less extensive than the tremor. Both Cohn and Copland consider mer- curial tremor as an example of paralysis agitans. Frank^ relates the case of a widow, set. 40, who after exposure to cold on coming out of a vapour-bath was attacked with this disorder. The move- ments seem, however, to have been more active than usual, and as she recovered in no long time after cupping the spine it may be doubted how far the case is comparable to the chronic affection. It appears to me that the cases I have cited warrant the view that there exists a functional nervous affection which at least bears a very close resemblance to paralysis agitans. Between this state and chorea there is certainly no very material difference. From the success of the continuous galvanic current in Reynolds' case, and of henbane in my own especially after faradization and strychnine had failed, it seems probable that the disorder depends in some instances ' Schmidt's ".Jahrb.," vol. cxvii. p. 163. 2 Copland's Diet., art. Paralysis, p. 25. 168 PARALYSIS AGITANS. at least on increased excitability of the nervous centres of such a quality that it will not tolerate tonics, and requires rather calmants. This varying quality of nervous matter is just one principal thing that makes the treatment of epilepsy and its allied disorders so un- certain and diflScult. Whether the slighter forms of the affection may pass by long continuance into the graver and more incurable, attended with organic change, is difficult to determine, but I think it quite possible. The analogy of chorea, which, as we have seen, is complicated sometimes with decided morbid changes, is very confir- mative of this view. Prolonged restless excitement of the nervous tissue in the centres is very likely, as in epilepsy, to induce a local determination of blood which gives rise to slow exudation and indu- ration. It is somewhat remarkable that these changes affect the same localities in paralysis agitans, as they do in epilepsy. The wide difference between the irregular purposeless tremors of paraly- sis agitans, and the strong, steady contraction of a muscle in volun- tary effort needs no exposition. It is clear that no theory can be correct which would class them together, because in both there is muscular action. The one circumstance common to both is that some disturbance of the molecular state which the nerve-cells assume during quiescence occurs in each. In the one this disturbance is perpetual except during sleep, owing probably to deranged nutrition of the nerve-cells. In the other the disturbance is regulated by the wnll, and is compensated by sufficient repose. The tendency of a habit of action, as well insisted on by my friend Dr. Sieveking, to perpetuate itself and become inveterate is not to be left out of account. The tremor, which at first, excited by some casual cause, might by appropriate means have been stilled permanently, when allowed to become habitual exceeds our power to control. The treatment of paralysis agitans in its earlier stages must I think be substantially the same as that of chorea. In its later, though there can be small hope of benefiting the patient materially, I should use hydr. bichlorid. in tr. cinchon. with ol. morrh., and sulphuret of potassium baths. As mercurial tremor has been alluded to above as a species of paralysis agitans, a view in which I quite coincide, I will observe here that mercury may be regarded with good reason as a very poison to feeble nervous systems. The disorder of the motor nerves which it produces is essentially a chronic affection, as evidenced by the similarity of the symptoms, the existing debility, the "Igedentia," and the " juvantia." Dr. Watson writes that it is aggravated by all kinds of mental emotion, and relieved temporarily by anything that tends to stimulate and fortify the nervous power. Steel is one of the best remedies for this disorder as it is for chorea and other neuroses. The inflammation of the buccal mucous membrane induced by mercury is evidently not of phlegmonous character, but of diffuse, and quasi-erysipelatous. It may be referred, I think, very reasonably to a paralysis of the vaso-motor nerves of the part. SPASMODIC AFFECTIONS. 169 Eczema mercuriale is a similar affection of the skin ; it is apt to be attended with adynamic fever, and sometimes with delirium and convulsions. The practice of taking or giving frequent blue-pill aperients is worthy of all reprobation. CHAPTER XVIII. SPASMODIC AFFECTIONS. IIypercineses, as Romberg terms them, seem to be of rarer occur- rence than the corresponding hypersesthesige. The same may be said of the kindred paralyses as compared to aneesthesia and neuralgise. This is somewhat remarkable inasmuch as in organic disease the rela- tion is reversed, motor power is much more frequently impaired than sensory. In many cases spasms depend on some organic alteration, but in quite as many they are independent of it. They present two principal forms, viz., clonic and tonic; the latter are more often the result of asthenic excitement than the former. In all spasms there is a defect of volitional power, the cerebral centres no longer rule the actions in an orderly manner, and some of the lower centres seem to have usurped their authority. In some instances the emotional are the seat of morbid excitability, in others the spinal. Often the excitability is intimately connected with debility, but this is by no means necessarily the case. Remote irritation, in the intestines or elsewhere, is a frequent determining cause of the spasm. Romberg in his first volume has given one of the best accounts we possess of the different manifestations of spasm. I shall notice briefly in this place the less commonly recognized forms, having described the classical elsewhere. Trismus is a clonic or tonic spasm of the muscles concerned in the movements of the lower jaw, and sometimes of the adjacent. It may be produced in predisposed persons by cold. One of Romberg's patients, a male, set. 43, is subject to a dying away in a marked degree of the upper and lower extremities accompanied by numbness of the muscles. At the same time the masseters and the tongue become rigid, and there is dysphagia. These symptoms are brought on immediately by exposure to cold. Evidently spasmodic contrac- tion of the arteries of the limbs coincides, in this instance, with a like state of the masticatory and lingual muscles. Various other causes may produce trismus, as dental and intestinal irritation, epi- lepsy, the gouty diathesis, abscess in the abdominal parietes, and hyper-excitability of the nervous centres. Dr. Eraser relates a case of severe trismus resulting from exposure to wet and cold, which was treated beneficially with Cannabis Indica given in gradually increased 170 SPASMODIC AFFECTIONS. doses up to gr. iij, o. li. He improved gradually, and made a good recovery. (V. Med. T. and Gaz., Feb. 7, 1864.) Facial spasm may show itself in one or several of the muscles supplied by the seventh nerve. It may aifect the orbicularis palpe- brarum alone, or the buccinator. A patient under my care, suffering with periodic frontal neuralgia attended with giddiness, had also twitching of the left eyelids. The pain and giddiness were cured by iron -\- quinine, but not the twitching, nor was the endermic ap- plication of morphia more effectual. A lady, who had had chorea when a girl, and whose nervous power was weak and overtasked, suffered with twitching of the face, her mouth being frequently drawn awry so that she had to hold it with her hand to steady it. She was wonderfully better in frosty weather. Immediately on eating, her face and neck became quite flushed and crimson. Here we have a paresis of arteries associated with a clonic spasm of ad- jacent muscles, the vasomotor and musculo-motor nerves being no doubt in a like state. MitchelP records the case of a female, aet. 60, in whom the muscles of the face, and tongue, and neck on the left side were affected at intervals of ten minutes, with rigid spasm lasting for three minutes at a time. The left side of the nose and chin was numb, the teeth were closely compressed, the nose was drawn over to the left side, and the forehead and eyebrows corru- gated. The muscles of the neck rotated the head to the left shoulder, the left arm became extended, and a sense of numbness ran down in a straight line from the neck to the thumb and forefinger. The disorder ceased after the extraction of all the carious teeth. Rom- berg had under his care a robust man, set. 36, who after a powerful mental emotion was attacked with slight paralysis of the left side. This disappeared after bloodletting and purging, but violent spasm set in, affecting exclusively the left half of the mouth and the pla- tysma myoides ; it persisted for four days and nights, and gradually yielded to cupping and tartar emetic, and the endermic application of morphia. Oppolzer^ relates a case in which along with pain of the right side of the head and face, and right shoulder twitchings occurred in the facial muscles, the sterno-cleido-mastoid, the muscles of the external ear, and those of the shoulder. The muscles of both external ears were affected, the right most. The twitchings were attended with severe pain which preceded and outlasted them. Pres- sure on any part of the face, or head, or shoulder, arrested the twitchings, but not the pains. Volition also controlled the spasms. In the preceding cases we have examples of the causation of facial spasm by simple nervous hypersesthesia, by remote irritation, or by sthenic excitement of the brain (probably). It is evident that much discrimination is requisite to judge correctly of the pathological state. Strabismus is sometimes a spasmodic affection, and is produced 1 "Med.-Chir. Trans.," vol iv. p. 25. ^ "Wien Wochenbl.," 6—8; 1861. SPASMODIC AFFECTIONS. 171 by dental or intestinal irritation, by inflammatory disorder at the base of the brain, and by any emotions which temporarily derange mental equanimity. Bohm states that idiots whose eyes were in a normal state at other times squinted egregiously while engaged at their lessons. As the cerebral power increases the squint lessens and disappears. This seems to indicate a diversion of vis yiervosa from the centres of the ocular nerves to the weak and struggling hemi- spheres. The same author relates an interesting instance of the replacement of ague paroxysms by spasmodic strabismus. The type was at first quartan, then tertian, and lastly quotidian. The muscles of the neck are not unfrequently affected with spasm, which is often produced by rheumatoid influences, but in other cases, as in that related by Brodie, where a wry-neck alternated with melancholia, seems to depend on dynamic nervous derangement. In one of Romberg's cases dentition was evidently the cause of the spasm. In a weakly girl, set. 7, under ray care, there was very marked tonic contraction of the left sterno-cleido-mastoid. The head was drawn to the left, much more so at some times than at others. Under the use of iron, ether, and valerian with veratria ointment locally the spasm ceased, recurred again with earache, and ceased again under the administration of pot. iod. + ammon. carb. There was a rheumatic element in the case as evidenced by some affection of the feet. The two following cases are instances of spasms probably originat- ing in the upper cervical region of the cord, of very obscure causa- tion, and but little modified by treatment. No. 78.— E. B., get. 43, seen Oct. 3d, 1862. Has been affected for about twelve months as at present, his health, however, remaining good. Is a broad-made man with rather short neck, works at china-riveting, and thinks his work may have something to do with the disorder, as he sits with the right side of his head facing a window, and has to turn frequently to the left. He is subject to almost continual clonic spasm especially of the left sterno-cleido-mastoid and trapezius muscles, by which the head is bowed to the left side and the shoulder is raised. Any mental excitement increases the spasm greatly. He is much worse sometimes than at others. He has a sensation of cramp in the left neck which extends down the outer side of the same arm, and is relieved by stretching it out. The muscles of the right side of the neck do not appear to be paralyzed j he can straighten his neck occasionally by a voluntary effort. In June, 1863, he had an attack of rheumatism of the right leg. April 5th, 1864. Is much better since he went down to Brighton last autumn and had sea-bathing ; while in the water he was quite free from spasm, and so he is now in the morning and when he is warm, but on cold, wet and foggy days he is worse. The spasm is very much less than it used to be. Much treatment was employed in this case with but little advantage, he took ferri carb., zinci valerian., tr. aconiti, pot. iod., and citrate of quinine and iron, but with very little advantage. Sub- cutaneous injections of atropine and opium were fairly tried, but they dis- appointed my expectations. Galvanizing was apparently of benefit, the antagonist muscles being faradized, and the affected ones subjected to a 172 SPASMODIC AFFECTIONS. continuous current. This was done under Mr. Lobb's supervision. On tbe whole I think the " vis medieatrix" had as much share in the improvement as the remedies. The affection seems to be specially referable to excitement of the left spinal accessory nerve, but there is nothing to show how this originated. May not such states of excitement arise in nervous centres apparently sua spnnte, just as they seem to do in centric epilepsy ? No. 79.— St. W., get. 33, f., seen Nov. 14th. Aspect " spiritual."

At times has paroxysms of violent spasmodic contractions of the diaphragm resembling hiccup attended with constant expectoration of white frothy mucus. I witnessed one of these, which lasted some minutes and appeared very distressing. They continued sometimes a quarter of an hour and were succeeded by sensations of sinking. The vibratory movements of the head from side to side were much more continuous than the spasms of the diaphragm, they occurred sometimes while she was lying down. There were sometimes intervals of four to eight days between the paroxysms. During one fortnight they occurred very frequently, she could not take any- thing even water without bringing them on. Her nights were restless. She had sometimes pain and throbbing in head. She could not walk without some slight assistance, as a finger held out to her. Her disorder did not seem to be at all simulated, in fact both the cervical and the diaphragmatic spasms were clearly involuntary. She remained under obser- vation till towards the end of the succeeding March and was then dis- missed materially improved ; she could walk a good deal better. The chief remedies employed were aperients, citrate of iron and quinine, and iron electuary. The pulse varied from 108 to 132. It seems most probable that this was a dynamic disorder, and also that it was not dependent on remote irritation. Had it been otherwise the progress would rather have been to worse than better. I think we must assume the existence of a state of erethysm of the cord in the vicinity of the origin of the phrenic and upper cervical nerves. Counter-irritation in both these cases would probably have been advantageous, in fact in the latter the head was much quieter some time after a blister to the loins. The following case was, I think, closely related to neuralgia, or at any rate to neuralgic disorder, judging from the aneesthesia and the " juvantia." It was probably a peripheral neurosis, but is of interest specially as showing the affinity between spasm and paralysis (sensory). No. 80. — A. N., f., set. 17, got suddenly spasmodic contraction of the flexor muscles of the left hand and forearm a week before she came under Mr. Bryant's care. The health was good, catamenia regular, sensation of the parts perfect. Iron was given, and in three weeks the natural move- ments of the part were restored; the nerves of sensation, however, now became involved, complete anaesthesia of the whole hand and forearm making its appearance. This condition also disappeared in two months under the same treatment, sensation and motion being at last perfect. (V. lied. Times and Gaz., 1862, June 14th.) SPASMODIC AFFECTIONS. 173 The affection termed writer's cramp seems to depend on undue excitability of the muscles and nerves concerned in writing, such that they are unable to execute the necessary delicate movements, but start off into larger ones. When much engaged in writing during cold weather I have experienced a tendency to it, which makes it needful to write more slowly and steadily in order to keep the muscles under control. There is at such times a sense of fa- tigue in the hand and wrist, and for some way up the arm. Zura- delli considers that there is primary paralysis of some muscles, and secondary spasm of others, and that various forms of the disorder may occur according to the particular muscles affected. Thielmann relates a case of similar disorder occurring in a sempstress. When she attempted to sew, the thumb flew away from the needle, and a burning pain extended up along the outer side of the wrist to the elbow, and if the effort was continued a red streak formed in the same situation. She was cured in twelve days by quinine and opium. Haupt states that other neuroses are not infrequent as complications of writer's cramp. He mentions squinting, stuttering, choreic disorder, laryngeal or pharyngeal spasm, strangury, palpi- tation of the heart, solar plexus, neuralgia, headache, &c. Rheu- matism appears to be one of the inducing causes, over-exertion of the muscles concerned, and general impairment of nervous power in- ducing undue excitability are also powerfully influential. It is evident that resting the enfeebled part is necessary, and in many cases if not indeed in all, I should strongly advise the patient to discontinue entirely writing with the affected hand, and to accustom himself to use the other. This would not cause much inconvenience after a few weeks' practice. Pitha relates a case cured by electri- city. Chorea, which is so analogous a disorder, is sometimes so much benefited by faradization, that I should expect much good from the same means in writer's cramp. Dr. Althaus employs the interrupted current when the disorder appears to be paralytic, but the continu- ous if it is spasmodic. I have no doubt that the latter remedy is especially indicated in spasms due to sthenic excitement, but where the condition is rather one of hypersesthesia and debility the stimu- lus of the interrupted would be I think more beneficial. It is cer- tain that some spasms are cured by stimuli. Tonic or sedative treat- ment internally would also be very advisable. In cases where there was any indication of a rheumatic element potass, iod. usually with ammon. carb. should be administered. Cold douching would proba- bly be beneficial, and local bathing with sulphuret of potassium lotion. Spasms of the muscles of the lower limbs, especially of the gastrocnemii, are not uncommon, and give rise to various distortions. Remote causes of irritation are probably the most frequent, but in some instances there is centric disorder. It is remarkable that in some cases the weight of the body pressing on the feet against the ground seems to have induced the spasm which was absent in the 174 SLEEPLESSNESS. recumbent posture. This illustrates the reflex production of certain distortions. Bamberger relates the case of a youth, set. 19, conva- lescent from pneumonia. As soon as he touched the ground with his feet all the muscles of the lower extremities fell into a state of tetanic rigidity, interrupted by the most violent sudden contractions, which threw the patient upwards, and during their rapid recurrence increased in intensity so that the patient had to be supported. At the same time the face was flushed and distorted, the pulse accele- rated and extremely forcible. The moment that the patient sat or lay down all the movements ceased. If while lying in bed the soles of his feet were pressed, the same phenomena appeared but with much less intensity. He was cured by sedatives and cold affusion {v. Schmidt's Jahrb., vol. cii. pp. 23, 24). The congenital development of pes equinus, &c., which is not infrequent, stands probably in connection with the greater tendency to reflex action during fcetal life in consequence of the imperfect control exercised by the brain. The most practical facts to bear in mind with reference to spasms are, (1) their frequent dependence on some removable cause of irrita- tion ; and (2) that when there exists no such exciting cause the quality of the nervous derangement producing them may be very various, either sthenic requiring depletion and counter-irritation, or hypergesthetic calling for sedatives, or connected with exhaustion and needing stimulants and tonics. It may be no easy matter to estimate correctly the existing pathological state. Mr. Smith, of Leeds, finds that permanent involuntary contrac- tion of muscles may be successfully treated by the following simple proceeding. Place their origin and insertion as far apart as possible ; maintain them in that state for some time, their oppo- nents will then be gaining strength, and the balance of power will be restored. He states that he has cured cases of spasm of the masseter, sterno-cleido-mastoid, and various other muscles by this means. {Lancet, Sept. 20th, 1851.) CHAPTER XIX. SLEEPLESSNESS. The requirements of different individuals with regard to sleep differ considerably. Some are able to do with comparatively little, others need much more. It is generally those of great mental and nervous energy who at any rate for a certain ,time can bear the privation of their ordinary repose. Alison says of Napoleon, that like Wellington and all great generals he had an extraordinary SLEEPLESSNESS. 175 power of commanding sleep when it suited him to take rest, and of doing without it when circumstances required such a privation. Boerhaave, according to Forbes Winslow, is recorded not to have closed his eyes in sleep for a period of six weeks in consequence of intense study. We may perhaps take this account cum grano salis, as we read in a note of the same page that a Chinese criminal lived but nineteen days when condemned to be put to death by being kept constantly awake. There is, however, no doubt that in the state of mania patients will pass an extraordinary length of time with little or no sleep, and that all very strongly exciting passions and emotions will have a similar effect. The above remarks may seem to show the propriety of distinguishing a sthenic variety or form of sleepless- ness depending on cerebral excitement, or on a state of semi-inflam- matory irritation. It has much in common with the sthenic form of delirium tremens, and occurs in various fevers, in inflammations of the cerebral membranes, and in commencing insanity. Mr. Solly reports a case where repeated copious leeching with purgation fol- lowed by gentle mercurials and aconite produced sleep in about five days, of which otherwise there was but little prospect. Dr. Graves also mentions a case of delirium tremens in which watchfulness was a prominent symptom, but disappeared rapidly under the use of tar- tar emetic with opium. Such cases are, however, comparatively rare with regard to those of the opposite type where the sleeplessness is dependent upon a state of debility and irritability induced by bodily or mental causes. Dr. Russell has published an excellent paper^ in which he illustrates forcibly the powerful influence of mental excitement and trouble in causing sleeplessness. The eff'ects of such inflictions are only too familiar, and too often are the secret cause why the best therapy proves inefficient. When, however, the depression is not yielded to and encouraged, or is not too over- whelming in proportion to the strength of the system, judicious medication may often do much to make the burden less felt, the edge of the sorrow less keen. It is most true, and Dr. Russell illus- trates it well, that the feeble hypersesthetic brain collapses under the pressure which an organ of better quality and power can sustain. Now we have means whereby we can often improve this quality and power to a greater or less extent. Further, the mere procuring a regularly recurring oblivion of distressing impressions is no slight boon, and makes the suff'erer more capable to bear his waking bur- den. Our nature is so compounded of the material and immaterial that what benefits the former is almost certain to do the same to the latter. A girl recently under my care with very various and marked signs of prostration of nerve-power suff'ered for many months with exceedingly restless nights, the cause of which appeared to be chiefly great hypersesthesia. Although she improved materially in other respects she did not sleep well until she was removed from » "Brit. Med. J." 1861 ; May 25th, Nov. 9th, 16th. 176 SLEEPLESSNESS. London to a healthy part of the country. I have had several patients, two especially, both temperate males, who for a length of time were quite dependent for good rest at night on wine taken either on going to bed, or in the course of the night. Graves mentions that in per- sons of irritable and nervous disposition he has found musk or assa- foetida given more or less frequently during the day effectual in procuring sleep at night. In some cases of this kind it answers well to divert the patient's attention from the idea of remaining sleepless by giving it a new direction, as the importance of being awake to take his medicine at fixed times. In others a placebo, such as a bread-pill, proves a powerful sedative if only the patient can be inspired with faith in'^its efficacy. Dr. Lay cock mentions a case where so long a sleep followed such a medication that it excited alarm. It is not easy to form a precise idea of the state of the nervous centres in which "a night-cap," as above mentioned, is so effectual in procuring sleep. Debility is certainly one marked fea- ture of it, but there must be surely another, even more important, as the most profound debility does not by any means always inter- fere with sound sleep, nay, rather seems to conditionate it. This other element we are much disposed to think is hyperaesthesia, or irritability, which as already noted so commonly increases pan passu with weakness. The condition may be compared with that of neu- ralgia when it is beginning to give way under treatment, and is so easily reproduced by anything that causes exhaustion. Now as the stimulant recruits the exhausted nerve-force the hyperaesthesia ceases, and the brain-tissue subsides into a state of calm repose. It may be added here that it is often well to give not only a stimulant, but also some digestible nourishment, about the time of going to rest, or even in the course of the night where debility to a serious extent exists. It is quite certain that a craving empty stomach is by no means favourable to quiet slumber, and in this point of view moderate suppers are far from being unsuitable to many invalids. I well remember the case of a lady, who the night after a natural confinement woke up with severe gastric disorder and flatulence, which resisted various medication, but subsided immediately after a plate of cold meat, and some brandy-and-water.^ Among the various soporifics I doubt if there be any more potent, especially for the weakly and hypersesthetic, than prolonged exposure to the cold open air. This should be so managed as not to cause great fatigue, and if well timed, and followed by a sufficient meal, it will be found an admirable preparative for sound nightly slumber. Where this is impossible, as in cases of severe disease, and especially where, as often happens, narcotics disagree, it is well to try the effect of a monotonous voice. There is no question as to the soporific influence of such tones particularly when the speaker or reader is detailing ' A medical friend informs me that he finds a mustard poultice to the epigastrium an excellent hypnotic in some cases. This probably depends on its stimulating a lan- guid solar plexus. SLEEPLESSNESS. 177 some matter ^vllicll is not without a considerable tinge of dulness. The old monk's prescription for sleeplessness, viz., to tell your beads, was sound advice. The removal of any existing cause of irritation is of course often essential to procure sleep. Surgical cases exem- plify this well. A gentleman about whom I was consulted lately told me that while suffering with torpid liver in India he had no sleep for five months until he commenced the nitro-muriatic acid bath and sponging. He thinks that he never slept an hour, and besides bad lost taste and smell. He had no jaundice all this time, but objects appeared yellow to him. In less than a fortnight the function of the liver was restored, and with it the senses of taste and smell. Then followed sleep, at first for thirty hours on end, and in six months he was in perfect health. The conditions necessary for the sleep-repose of the brain seem to be essentially these two, (1) a non-excited or active state of the cerebral tissue ; (2) in most cases a diminished aflux of blood to the organ. We have already sufficiently noticed the importance of the first ; the following observation illustrates well the need of the second. A gentleman, set. 24, after considerable mental strain, experienced the following symptoms. He was thoroughly weary and drowsy at the close of the day, and felt, as well he might, the need of nature's restorer; scarcely, however, had he laid down his head, when the cerebral arteries began to throb forcibly, and soon all inclination for sleep was banished, and for hours he lay wide awake but deadly weary. The causa niali here was evidently defi- cient tonicity in the cerebral arteries, or more exactly paresis of their vaso-motor nerves. As the arteries relaxed they admitted an undue flow of blood to the brain which goaded its weary tissue into abnormal activity. The effect of altered blood-flow on the brain is also apparent in the following account which Graves quotes from Vigne's work. He states that in Kashmir it is a common practice for mothers to put their children to sleep by exposing the head for two or three hours to a small stream of water. This, as in Brown- Sequard's and Tholozan's experiment of lowering the temperature of one hand by chilling the other, must certainly have the effect of causing cerebral anaemia by contraction of its arteries. In children, attacks of malaroid remittent, a disease I shall subsequently describe, are invariably productive of very marked sleeplessness. The noc- turnal febrile paroxysm seems to generate a state of excitability of the brain, and at the same time to stimulate it to morbid action by accelerating the circulation. Quinine in these cases is a most efficient hypnotic. Adults also occasionally suffer much with rest- lessness at night in connection with obscure aguish phenomena, as chills, cold sweats, prostration, and feelings of alarm, or strange terror. In some instances of this kind there is that very peculiar sensation of dread which makes the person afraid to sleep lest it shiould be a sleep without waking. I have met with this in both sexes. Closely allied to the insomnia of fever is that which occurs 12 178 SLEEPLESSNESS. from over- fatigue, where the sufferer, though sorely in need of repose, lies vainly expecting it, and finds himself instead wakeful, feverous, and exhausted. Tea-drinking, though in moderation, will sometimes seriously interfere with sleep. I believe the following is an instance of its poisonous action when taken in excess. No. 81. — J. R., 3et. 47, m., a large stout man, works at a kila in a brick- field, ad. April 27tli. Ill one month. Complains of a tormenting feeling which goes all over his chest and head, and prevents sleep; when he does, he has terrific dreams. Does not suffer more after eating. T. clean. P. quiet. B. not regular. Sounds of heart normal. Sanguine aspect. Slight rheumatic pains in the knees. His symptoms did not vary much ; he con- stantly complained of a tormenting feeling "like evil spirits," referred to the praecordia, and attended with palpitation. He was besides weak, and had some tenderness of the scalp and some lichenous eruption once. I was quite unaware of the nature of the case, and gave him various medicines with little or no benefit till June 22d, when as he complained of being rest- less, at night I ordered him half a grain of morph. mur. o. n. and a mixture of tr. valerian, aramon. + tr. arniege + tr. opii ter die. He improved by this, and was quite well by Aug. 3d. His wife told me then that she had thought he was out of his mind; he vised to lie awake at night with- out sleep ; fancied he was going to be taken away to an asylum. He wanted to tell the hospital chaplain that he was going to be stoned. His illness began with nocturnal restlessness and sleeplessness. He was never a drinking man, but used to drink last summer three or four quarts of tea a day while at work. After his recovery he was conscious of his former delusions. From the praeeordial dyssesthesia, and the sleeplessness, and the good effect 'of morphia I am strongly inclined to regard the preceding as a tea-neurosis. The history is unfortunately deficient as to whether he had continued his copious libations of tea up to the time of his being taken ill, and as to whether he subsequently discontinued them, but the probability is that he made no change. In all obscure neuroses we ought to consider whether tea may not be the culprit. With regard to soporific drugs I think that henbane, In spite of the doubts which have lately been thrown upon its efficacy, approves itself frequently as a really valuable remedy. It seems to act as a direct cerebral calmant, affecting evidently the vaso-motor system in a much less degree. It is rare that it has any injurious effects, but I have met v/ith some very susceptible systems, who could not take it nor any other form of narcotic. The action of opium, on the other hand, though more potent, is more uncertain, and more apt to be injurious. It exerts unquestionably in many persons a stimulating power, at least when given in moderate doses, and in the early period of its action. Thus it comes to pass that if the cerebral tissue be highly hypergesthetic, opium, unless given in large doses, is apt to produce an effect the very reverse of sedative. It seems appropriate to cases where there is some but not profound debility, where the cause of the insomnia consists in some peripheral nerve irritation, where the brain is not highly hypersesthetic, where the secretions are tolerably free, and generally where there exists SLEEPLESSNESS. 179 any grave and severely distressing affection. When given to obviate sleeplessness of cerebral origin it should be administered in a suffi- cient dose some time before the period when it is desired, that its soporific action should be manifested. I quite agree with Dr. Graves as to the advantage of using it in the form of enema in many in- stances, and, as Dupuytren held, the dose need not exceed that which is given by the mouth. The administration of high doses of opium is one of the most delicate points of practice, and though in skilful hands it gives often excellent results, had better be avoided if pos- sible. The previous use of antimony, of a cold douche to the head while the body is immersed in a warm bath, or of the latter alone may render a smaller and safer dose of opium equally efficacious with a larger. The symptom which would most warrant the exhi- bition of large doses of opium is severe pain provided at the same time there were no indications of failure of pulse. Large doses of henbane, as gr. xx of the extract, may in many cases advantageously replace opium. I have recently given for several nights gr. xxv to a man on the verge of delirium tremens and sleepless previously even with morph. mur. gr. ^. When sleeplessness depends on some frequently-recurring irritation, as cough, much smaller doses of opium may be sufficient, and they may be repeated according to need. In maniacal excitement, as Dr. M'Leod'" has recently pointed out hydrocyanic acid in "Iv doses, frequently repeated if necessary, is often effectual in inducing sleep. Forbes Winslow says " a warm bath a short period before retire- ing to rest, bathing the head at the same time with cold water, par- ticularly if the scalp be unnaturally hot, will often insure a quiet and composed night, when no description of sedative, however potent its character and dose, would influence the system." {Led. on Insanity, p. 73.) In the foregoing remarks the nature and causes of drowsiness, which we meet with occasionally as an independent affection, have been incidentally noticed. In the great majority of cases it depends on cerebral debility or exhaustion, but in some I am pretty certain it is one of the results of angemia of the hemispheres. In these cases I believe it may be materially lessened, if not cured, by the administration of belladonna with the view of procuring relaxation of the arteries. In one instance, where drowsiness came on so much about 5 P.M. every day that the man was unable to go on with his work, I gave atropia gr. y^^ in infusion of valerian ter die with a curativ^e result. In another instance, however, the drug failed. On the other hand I do not deny that drowsiness may be associated with cerebral hypergemia, but this is almost invariably of a more or less venous character. I doubt how far an active cere- bral circulation ever coincides with drowsiness, except of course in cases of actual organic mischief. When drowsiness depends on » "Med.

He remained under treatment till the end of May and improved very decidedly. The state of the face did not alter much. He took strychnia gradually increased up to gr. y^2 ter die, besides quinine and iron. These remedies were certainly beneficial, which puts it, I think, out of the question that the drowsiness depended on cerebral hypersemia. Tonics would surely have aggravated the results of such disorder. On the other hand there were marked indi- cations of cerebral debility, and the state of the circulation in the face may be ascribed to paresis of the nerves of the arteries. I have notes of a quite similar case (externally) where there were no cerebral symptoms, only debility ; tonics were beneficial. These cases give us the practical hint not to conclude too hastily from the outside to the state of the inside. Soporose affections are stated by Schramm' to be of very frequent occurrence in the malarious district where he practises, especially in children. In them they are usually not serious, but in persons advanced in life they sometimes prove fatal. The sopor depends in some instances on cerebral anaemia, in others probably on a direct action of the poison on the brain. The following case has lately occurred to me. No. 83. — E. L., aet. 7, f., ad. March 21, ill four weeks.

In a gentleman lately under my care, sufl'ering with great exhaustion of nervous power and occasional neuralgia, extreme drowsiness was a marked symptom. In all cases of this kind where we have no reason to suspect narcotic poisoning, intracranial extravasation, or the like, we should look to the state of the urine, as latent renal degeneration might be a very possible cause of sopor. ' Bayer, Arztl. Intell. Bl. 38, 39, 40 ; 1861. FACIAL NEURALGIA. 181 CHAPTER XX. FACIAL NEURALGIA. There are several varieties of this form of affection, which it is practically important to distinguish. One is the sympathetic, or reflected, where the pain depends on some cause of irritation seated in a more or less remote part ; it may be a decayed tooth, and over- acid stomach, a gravid uterus, intestinal accumulations. Another is where the pain is produced by some organic central disease, as in Romberg's well-recorded case. A third is where the pain is associated with marked tenderness ; and where, judging from the " juvantia," we must consider the nervous disorder to be of a differ- ent kind to that which exists in other cases. It is clear that the conditions cannot be identical in cases which are cured by aconitine ointment, and those which yield to tonics. Fourthly, there are the instances which often are evidently produced by the special miasm which gives rise to ague, and which when their causation is not so evident are still attended with similar states of nerve debility, and are cured by the same means. These cases are sometimes markedly paroxysmal, sometimes show no periodicity. They are of very fre- quent occurrence in malarious districts ; Schramm observed 195 in the course of four years at Bodenwohr in the Palatinate. A transi- tion between the two last varieties is exhibited in those cases re- ferred to, by Watson and Brodie, in which after the pain has existed a long while the affected skin becomes swollen, red, and exquisitely tender. In these it is reasonable to suppose that the paretic state of the cerebro-spinal nerves has extended to the adjacent vaso-motor, in consequence of which the skin becomes highly injected with blood, and its sensory function is consequently exalted. Romberg terms the condition where the painful part is quite tolerant of pressure " ansesthesia dolorosa," which he regards as quite distinct from tic douloureux. Even in the fourth variety, however, there are many instances in which there is great tenderness of the skin without any vascular injection. With regard to the first form of facial neuralgia, I have chiefly to mention that while we should always have an eye to its possible existence, and be on the lookout for any indication of remote irri- tation on which it may depend, we should not be in the case of sus- pected teeth over-hasty to have them removed. It has occurred to me more than once to relieve effectually by medicine neuralgic pain on account of which several teeth had been fruitlessly extracted ; and on the other hand, the presence of numerous decayed stumps 182 FACIAL NEURALGIA. in the jaws has not prevented my curing a distracting neuralgia of the face and head. Dr. Brinton well remarks/ " There are plenty of facts which suggest that lesions of nerves not necessarily painful may become so from causes originally by no means local. Thus I believe there are hundreds of people walking about London this minute, the diseased nerves of whose carious teeth would be speedily roused into severe neuralgia by two or three nights of sleepless watching, and anxiety, or by two or three days of insufficient nour- ishment, or of violent and exhausting exertion of mind or body. And conversely I am sure that a generous diet will often relieve the agony arising from sheer involvement of nerves in a cancerous de- posit." The case related by Sir B. Brodie where a pain in one foot was immediately relieved by dilatation of a stricture of the urethra, which the patient had not even mentioned at first, affords a good example how latent and remote the real causa mali may be in all cases of neuralgia, and how carefully we should search for indica- tions of it. Friedberg records^ four cases of severe pain of the face, involving in three all the divisions of the fifth nerve, and refractory to all internal treatment, which at length yielded to the extraction of one carious tooth. The remarkable circumstance was that other carious teeth had previously been extracted without relief, though they were painful and aching, while the tooth which appeared to be the cause of the neuralgia was painless. I would say generally that in all cases where the general health and strength did not appear much impaired, I should think it very necessary to make particular inquiry after possible determining causes of the neuralgia. Oppenheimer^ relates two cases of neuralgia of the fifth pair which obstinately resisted all treatment until the condition of the nasal cavities was investigated. In the first case a male, set. 20, had regular paroxysms affecting all the divisions of the right nerve, which were cured by removing a nasal polypus that was accidentally discovered. In the second case there were very frequent and irregu- lar attacks of ill-defined pains, which were materially relieved by zinc injections into the nasal cavities. These were not, however, adequate to curing completely the catarrh, which persisted along with the pains to some extent. With regard to facial neuralgia depending on central alterations of structure, I do not know how it is to be diagnosed unless there are existing symptoms of sucli disease, as paralysis of some limb or group of muscles. Inefficiency of all remedies would of course make it highly probable that some organic alteration was at the bottom of the mischief. It is, however, worth remarking that even in such cases remedies may produce a certain amount of benefit. Thus in Romberg's case, sesquioxide of iron and assafoetida at first proved 1 " Lancet," April 11th, 1863. 2 Canstatt's "Jahresb.," 1860, p. 25, voL iii. Schmidt's "Jahrb.," vol cviii. p. 178. FACIAL NEURALGIA. . 183 very serviceable. In the cuse of a fem-ile' who had long suffered from intense pain in the balls of the toes, depending, as the result proved, on a bony tumour in the internal popliteal nerve, relief was always derived from arsenic, though it was transient. The third form must, I think, be rare ; I have scarcely met with a marked example of it, though analogous hyperaesthesias in other situations are not uncommon. A typical case of this affection would, I think, occur in a person of tolerably good health and strength in whom tonics did not appear indicated. Such a one Mr. Skey's patient seems to have been whom he treated in St. Bartholomew's with aconitine ointment. He describes him as a fisherman, set. 40, of dark, swarthy complexion, apparently of healthy constitution, and not intemperate, (V. Med. Crazette, vol. xix. p. 158.) It is proba- bly in cases of this class that two remedies which have been highly recommended for their occasional success may be expected to prove beneficial. I allude to muriate of ammonia, and croton oil. Mr. Skey found the former of more benefit in Mr. Spey's case than any other internal medicine, though the good effect soon failed. Barra- lier recommends it to be given during the paroxysm at half-hour intervals. Besides the temporary relief it was observed that in cases of headache returning in periodical paroxysms several times a month the intervals gradually became longer, the attacks diminished in intensity, and ended by disappearing completely after having been several times arrested by the remedy. It has proved effectual in idiopathic hemicrania, in headache consequent on recurring ague, in those occurring in the decline of low fevers, and in the period of irritation in typhus. (V. Edin. Med. Journal^ ^ug. 1859.) It is a remedy which would certainly not avail in cases suitable for quinine and iron. My chief acquaintance with it is as a remedy for muscular rheumatism. I have found it useful in one case of abdominal neu- ralgia, but my experience of it as an antineuralgic is very limited. With regard to croton oil our knowledge is purely empirical ; we know that it has achieved great results in a few cases, but we have scarce any indications to guide us as to the state of system to which it is appropriate. A priori we may suppose that constipation, and an absence of prostration would be prominent features of cases where it was to benefit. The following case belongs rather to the transitional instances above alluded to, than to this form. No. 84. — J. R., ad. July 25th. Ill two months, worse last three weeks.

He was almost free from pain in a week after treatment was commenced, but he was still weak when he ceased attendance Sept. 4th. In about eighteen months he came under my care again with the same disorder. He mentioned now that his head felt hot ; he could hardly bear to lay it on the pillow, it was so sore. After a fit of pain he trembled all over. He had six decayed teeth, but felt no inconvenience from them, except perhaps that he could not drink hot liquids. He ceased attendance much relieved in five weeks. In about two years he was again under my hands with the same symptoms, great soreness of the head, and inability to take hot ingesta into his mouth. He was quite cured in five weeks, and I have not seen him since (three years ago). His treatment consisted of quinine and iron, arsenic and belladonna. The latter seemed perhaps even more efficacious than the former. This man had very much of the stamp of aguish disorder upon him, as marked by great general debility, nocturnal sweatings and "cold shivers" which at one time succeeded each fit of pain. The cutaneous hyperaesthesia was well marked, but it yielded to the same remedies which subdued the pain. The presence of the decayed teeth did not prevent the final cure. The relapsing tendency of the disorder was very marked. The last form is certainly far the most frequent, and corresponds with the most frequent forms of neuralgia in other localities. Schramm^ finds the disorder to prevail much more in the female than in the male sex in the proportion of 186 to 69. In the former the disease increased in frequency up to the 30th year, in the latter up to the 40th. More cases occurred in the first than in the last six months of the year, 72 from January to April out of 195. The kind of pain varied very much ; it was often attended with indica- tions of vasomotor paresis, injection of the eyes, redness and swell- ing of the skin, lachrymation and salivation. Most cases were apyretic, but in several there was shivering and fever, or shivering and sweating. Sometimes the neuralgia suddenly replaced a pneu- monia, or a gastro-enteritis, or other inflammation. Supra-orbital neuralgia was always very obstinate. Arsenic was found an invalu- able remedy in such cases, and where there was a tendency to relapse. It also appeared to be a specific in chronic inflammation of the eyes and of the lids. The treatment of this kind of facial neuralgia, and of similar in any part, may be thus formulated. Either quinine is to be given in full rapidly repeated doses until deafness is produced, and afterwards in smaller doses : or, arsenic in doses of gr. o'o dissolved in distilled water by heat is to be taken ter die, and extr. belladon. in doses of gr. ^-gr. 1 2dis horis until either the pain yields, or disorder of vision and dryness of throat ensue. Both of these modes of treatment are thoroughly efficacious, but it is of little use in severe cases to adopt half measures. Rheumatic neuralgia of the face rarely, I think, corresponds to the course and distribution of the divisions of the fifth, but is more purely a peripheral aff"ection. The following case seems to illus- trate this. ' Schmidt's "Jalirb.," vol. ciii. p. 177. FACIAL NEURALGIA. 185 No. 85. — A returned Indian officer, set. 65, came under my care on account of some diffused swelling and redness of the nose and left eye. The nose had a bulbous appearance. He has never had gout, nor had any of his family. The affection was of three or four days' duration. He took pot. iod. + pot. bicarb. + ammon. carb., and in six days the disorder had ceased, but the previous night he had a good deal of pain in the left jaw and teeth. This was doubtless a rheumatic neuralgia, as the original affection had been a rheumatic inflammation. The following case is a good illustration of the fourth kind, I am indebted for the report of it to my friend Mr. Smith, of John- street, under whose able care the patient was. No. 86. — Mrs. S., set. 39, mother of seven children, the last born nine years ago; she has never been pregnant since till last autumn (1856), when she miscarried at the second month. Is very stout and leucophlegmatic, circulation languid; left eye often somewhat everted, especially when she is weak and tired. Is hardly ever free from pain in the head. Comes of a nervous family ; one sister, ast. 42, has never menstruated, and has now mental delusions; another has been epileptic for sixteen years, and is hysteri- cal in the highest degree ; a third is subject to neuralgia, and has a east in one eye; a brother is also neuralgic. Mrs. S. suffered at Hampstead, where she had been living several years, about fifteen years ago, a fearful attack of " tic douloureux" for weeks, and was only cured by Dr. Elliotson giving gr. xx doses of quinine till she was quite deaf; she was then quite cured. She has had slight attacks since, one rather severe at Marlow eight years ago. After miscarrying last autumn went to Scarborough for two months and got pretty well. Nov. 10th, 1856. Has neuralgia of left side of face, principally in the situation of the mental nerve, of moderate severity. Quinine was given at first in rather small, subsequently as the paroxysms became more severe and of longer duration, in larger doses until 48 grains were given in the twenty-four hours, when she became quite deaf, and the pain quite ceased (15th). The day before she was delirious and suffering fearful pain. This evening at the usual hour of paroxysm she had shiver- ing, but no pain. For two hours there ensued an attack of hysteria with partial syncope, only relieved by stimulants in large doses. 18th. For the last three nights has had similar attacks coming on at precisely the same hour with shivering, but gradually decreasing in severity. The amount of quinine has been diminished ; she takes 10 or 12 grains in twenty-four hours with as many drops of liquor arsenicalis. 22d. Hysterical attacks quite gone, slight pain in the face. She slowly gained strength, went to Brighton, and improved, but had still in spite of quinine slight returns of the disorder. Towards the end of the succeeding January she had neural- gia again in the same part, not paroxysmal, and not attended with shivering, but with some numbness extending down the right arm. The attack yielded to 24 grains of quinine in the day. Various external applications were tried, as opium, chloroform, belladonna, Fleming's tincture of aconite, Mor- son's aconitine ointment, but none of them afforded so much relief as poppy fomentation applied almost boiling hot. Remarks. — There are several points well worthy of notice in this highly interesting case. (1) The liability of the patient by original constitution to derangement of the nervous system, and the affinity clearly indicated between neuralgia, epilepsy, insanity, and hysteria, all varieties of dynamic disorder. (2) The resemblance of the 186 FACIAL NEURALGIA. affection in many respects to disease of malarious origin ; this resemblance depending, I believe, on the circumstance that the same structures are the seat of morbid action in both cases. Nerve debility, however produced, easily generates neuralgia. (3) The hysterical attacks which ensued as the neu- ralgia ceased were evidently a part of the same disorder, and were subdued by a continuance of the same treatment. They were surely as much a physical disorder as the neuralgia itself. (4) The involvement of the hemi- spheres in the morbid action when it was at its height, and the cessation of both pain and delirium under the same remedy. The nerve and the nervous centre suffered alike, but expressed that suffering differently. (5) The evi- dence the case affords, by the subsequent recurrences at intervals after the first attack, that the remedy which proved so serviceable did not remove or destroy the cause of the disease, but simply rendered the system more capa- ble of withstanding it. The long periods during which she was free from disease prove, I think, that it was not dependent on any structural lesion. I have lately treated in a similar way a female, set. 33, who had been suffering with facial neuralgia six months, and had taken qui- nine under medical advice without benefit. The pain occurred about twice a day in paroxysms of such severity that she became quite beside herself. She found that stooping forward, so as to pro- mote the flow of blood into the head, relieved the pain. The pain was speedily arrested by quinine gr. v %iis lioris till her ears were buzzing. Other tonics were given afterwards and the improvement has been maintained. She attributed the attack to sleeping in a damp bedstead, but she had also suffered much mentally, which was probably the more efficient cause. The following case illustrates the efficacy of the other mode of treatment alluded to. No. 87. — H. W., set. 4-5, m., ad. under Dr. Markham's care Feb. 9th. He was suffering severely, and was very much relieved by iron and quinine, and a liniment of chloroform + aconite. His symptoms relapsed after re- suming work at shoemaking. Dr. Markhara kindly transferred him to my care Feb. 29th. His history was that he had been ill quite five months, with pain in face and head ; he had some decayed teeth removed from left upper jaw, after which an abscess formed, but this is now quite well. The pain before the teeth were removed was toothache, not like the present, which he says is frightful, and worse than it has yet been. The pain is paroxysmal, it comes on the last three days about noon, and gets to its acme about 1 P. M., subsides about 5 or 6 P. M. It used to be very severe at night, but is not now. The pain affects both temples and all the top of head, is attended with a sense of opening and shutting, and with great sore- ness. The skin of the forehead is not more than just warm, not flushed or injected, but feels very tender. No pain now in eating. He feels very weak. Is not gouty, nor were either of his parents.

Head quite free from pain ; can't sleep at night for pain in anns if he works, but has no pain if he does not. Division of the suffering nerve is a remedy wliicli seems to have succeeded in a few instances, but has failed in many more. It can of course be useful only in peiipheral neuralgia, and I should think in states of system when the* general nervous power was not materi- ally depressed. The nearer to the point of exit of the nerves from the cranium the section is made the more likely the operation will be to prove beneficial, but it will be also much more severe. It is not to be thought of until all other means have failed. J. Kiihn' records an instance in which the inferior dental nerve was divided with apparent success, no relapse having ensued during six months at least. Ch. Frank^ records five cases, in four of which the opera- tion was successful. In the first, the second and third divisions of the fifth were the seat of disease. The infra-orbital neuralgia was cured by division of the nerve at its exit from the foramen, and the mental by section of the inferior dental nerve before its entrance into the canal. In two other cases the infra- orbital nerve was successfully divided. In a fourth the supra- orbital and frontal nerves were di- vided with good results. In the fifth case the inferior dental nerve was twice divided, at an interval of above four months between the operations, but the result seems not to have been satisfactory. Bratsch' gives the histories of nine patients, all of whom, except one, at the time of the report were freed from their sufferings. In several, however, the operation had been so recently performed that it was by no means certain that a relapse would not ensue, which indeed seems not impossible, seeing that the nine patients had shared no less than twenty-five operations among them, nearly three a-piece. Eisenmann remarks that these cases support the view that idiopathic neuralgias are of central origin, and agrees in the opinion attributed to Sir C. Bell that it is not the division of the nerve, but the operation, and its influence on the nervous centres, which removes the pain temporarily or permanently. Trousseau distinguishes epileptiform neuralgia, as he terms it, from ordinary facial neuralgia. The former is characterized by sudden violent darts of pain, attended in some instances with rapid convul- sive movements of the facial muscles, lasting about a minute, but returning ten to hundred times a day, with longer or shorter periods 1 " Archiv. Phys. Heilk ," iii. 1859, p. 226. 2 Schmidt's ".Jahrb.," vol. ci. p. 293. 3 Canst. " Jahresb." 1S60, p. 25. 18(5 FACIAL PARALYSIS. of exemption, varying in duration from days to months. The attacks are induced sometimes by any movement of the face, as in speaking, drinking, or eating. The suffering is terrible. No treatment cures effectually, but very large and repeated doses of opium procure, as long as they are continued, great mitigation of suffering, or even complete exemption. When the drug, however, is omitted, the disorder soon returns. Section of the trunk of the nerve also affords great temporary relief, lasting for days or even months, but the disorder recurs obstinately. Quinine is of no avail. HAPTEE XXI. FACIAL PARALYSIS. The plan of my work excludes from notice under this head all cases depending on organic lesion. Inorganic paralysis in this situ- ation has long been known, and designated as rheumatic. Trous- seau' says that the action of cold is one of its most frequent causes ; it surprises those whom it affects in the midst of most perfect health, and produces no derangement of the economy. A mere current of air, remaining in a damp place, as in a house whose walls are not well dried, is enough to give rise to it. Other causes are violent emotions, as terror, of which he gives an instance, anger, grief. Sometimes it comes on without apparent cause. Sudden superven- tion is a pretty constant character of this paralysis. J. Frank states that seven of his patients were suddenly attacked with this paralytic affection on putting their heads out of the window in the morning when it was very cold, though only for a moment. Romberg says, " It is very common for pain and tumefaction, accompanied by febri- citations, to occur in the affected side of the face after the patient has caught cold ; these symptoms disappear after a few days, and the paralysis remains." The facts above cited illustrate and con- firm, as it seems to me, the views already advanced as to the causation of paralysis. When the facial nerve is suddenly palsied by a " coup de vent," it is impossible to suppose that the cold has acted directly on the nervous filaaients lying well covered with fat and skin. On the other hand it is certain that the sensory nerves of the skin must be affected, and they produce the paralysis by a reflex inhibitory in- fluence. When the affection results from excessive emotions, such as terror whose enfeebling effect is notorious, there must be a direct paresis of the nerve-cells at the origin of the facial, unless we assume with Brown-Sequard that a spasm of the minute vessels takes place » "Clin. Med," vol. ii, p. 286. FACIAL PARALYSIS. 189 in this situation. The occurrence of quasi-inflammatory swelling in the afl"ected side of the face I should refer to a paralysis of vaso- motor nerves inducing hypersemia of the part. The paralysis in rare instances affects both sides of the face. (I am still confining myself to non-organic affection.) Dr. Gairdner relates^ and com- ments very instructively upon a case, which was entirely of eccen- tric origin. All facial expression is completely lost, and labial articulation also. According to M. Davaine, if the branches of the nerve given off before its exit from the stylo-mastoid foramen are paralyzed, there is also dysphagia, a nasal twang of voice, and im- pairment of lingual articulation. In the double paralysis the mouth is not drawn to one side, as it often is in the single. The diagnosis of inorganic from organic facial paralysis is a point of much import- ance. Romberg asserts that they are often confounded. Trousseau admits it possible that a facial paralysis, having all the characters of the disorder we are considering, may result from a very limited hemorrhage in the mesocephale ; though he adds that in all his prac- tice he has never met with such a case. He grounds his admission on Vulpian's experiments, who produced facial paralysis in a dog by a small wound of the fourth ventricle. The distinguishing signs which Trousseau confides in are the possibility of closing the lids in all cases of facial paralysis from cerebral disease, and the retention of the electric excitability of the muscles, which is lost in the func- tional disorder. In most cases of cerebral disease the facial paraly- sis will be associated with hemiplegia or other symptoms. If the facial nerve be involved in disease of the petrous bone, or have re- ceived traumatic lesion, the nature of the case is generally sufficiently clear. If there be any indications of inflammatory action in the vicinity of the parotid gland, we may apply a few leeches and purge. If, as usually happens, there are none, the interrupted current should be passed for fifteen minutes daily along the track of the paralyzed nerve, and stimulating embrocations should be rubbed on the skin of the face. Strychnia may be administered internally, or, as Trous- seau recommends, endermically. In exceptional cases the paralysis gets well in twelve or twenty-four hours of itself. Some cases, however, resist all treatment, though there is apparently no organic lesion. In some cases refractory to other remedies we may employ the continuous current. Schultz^ has succeeded in curing six cases of grave facial paralysis by this means. When the paralysis has been considerable and of long duration, it is apt to be followed, as in analogous instances, by permanent contracture to a greater or less extent of one or more of the facial muscles. Here we observe again the affinity between paralysis and spasm. I subjoin an illustrative case. ' V. <' Lancet," May 18, 1861. 2 "Wiener. Med. Wochenschr.," No. xxyii. 190 BETINAL HYPERESTHESIA. No. 88.— J. E. L., set. 22, m., ad. May 11th, ill one week. Has paraly- sis of the right facial nerve, the eye cannot be closed, and the cheek is puiFed out in expiration. He can close the mouth, but not so perfectly as normally. No numbness of skin of face. Hearing of right ear good. The affection came on quite gradually, after exposure of the right side of the face to a draught two days before. No pain in head. Some bad teeth, but none ache. He was faradized once, used linim. terebinth, to the face, and took strychnia, and was all but quite well in a month. He improved mate- rially with the liniment and one galvanization in the first three days. CHAPTER XXII. RETINAL HYPER.ESTHESIA. This common affection befalling one of the nerves of special sense corresponds closely in its essential features with the neuralgise. It is true that in most of the latter the disorder tends rather to the production of anaesthesia than of hyperaesthesia, and that we are not warranted in regarding the pain as a manifestation of the latter state. Still it is evident that the retinal affection occurs just in those states of system which are favourable to the production of neuralgige, that the general tenor of the concomitant symptoms is indicative of nervous prostration, and that the " juvantia" are pre- cisely those which avail to cure neuralgia. The term " scrofulous ophthalmia" commonly applied to the disease is, I cannot but think, a bad one, as it is not uncommonly met with in children who have no clearly marked strumous peculiarities, but who are weakly and cachectic. Very possibly it may be more frequent in strumous than in non-strumous children, but it certainly is not limited to the for- mer. It is remarkable that it should prevail so much among children ; it seems in them to take the place of the manifold sensory neural- gias which are such a plague to adults. The treatment which I have found most satisfactory is to apply an aconite lotion to the eye, and to administer ferri carb., or ferro-citrate of quinine with ol. morrh. A healthy state of the alimentary canal must of course be secured by gray powder, &c., if requisite. The following cases are instructive : — No. 89. — J. S., set. 10, m., ad. April 7th, with strumous ophthalmia, and treated with F. + Q- citr., ol. morrh., collyr. bellad. and blisters till 22d, when he was transferred to my care. He had then extreme photopho- bia, such that he had not opened the left eye for four months ; the right eye was almost as bad. He kept his hand constantly pressed over the eyes. He had suffered with the disorder for six years more or less since he had had hooping-cough. Pulse weak, jerky. T. clean. B. costive.

He then ceased attendance. Of all the above remedies, which were pretty fairly tried, there were two which produced signal benefit, so much as to make it worth while to notice them particularly. The first was tannin given in doses increased to gr. x ter die, with liq. opii sedat. n\^v ; under this the eyes almost perfectly recovered, and remained well for a month ; he was able to face the light well, and was in the open air all day long. After getting a wetting he relapsed, and the tannin failed to restore him. For a month he then took ferri pot. tart, and ol. morrh., but with no gain. I then gave the tr. fer. mur. itl x, 2dis horis, determined to see what a "coup sur coup" treatment would accomplish. In fourteen days he was able to bear the light quite well, and during the remainder of the time he was under observation (three months) no relapse occurred. I have no wish to exaggerate the efiicacy of these remedies, and have no expectation that liberal tanning and ironing of the system will always or often be requi- site. I should generally expect more good effect from a pure bracing air. Still I think the above example may be worth remembering in dealing with obstinate cases. The amount and frequency of the dose of a remedy are most important items for consideration, and are often by no means suffi- ciently regarded. Treatment may entirely fail from this cause alone.

She improved steadily from the time of commencing this medicine. She was seen again Nov. 21st, the eyes continued well, she had been in the country. These two cases were as nearly as possible exactly alike, save the difference of sex, yet the remedies which had availed most in the first were useless in the second. It seems to me that such experience as I have just recorded, which of course is frequently paralleled, affords us some valuable guidance in dealing with other disorders whose nature is more obscure, as epileptic affections, or other neuroses. It seems as if, though the kind of remedy is clearly indicated, it is a matter of exceeding difficulty to find that which shall be exactly appropriate to the particular instance. Not only so, but the amount of dose is a matter of material moment. I have seen a sixteenth of a grain of strychnia ter die cause considerable stomach disturbance, while one-twentieth was well borne and cured. Where nervous tissue acquires an extreme sus- ceptibility it is no easy matter to adjust a remedy so as to tone and calm without injuriously exciting — and this is what is wanted. If these points 192 RETINAL HYPERESTHESIA. were well considered, we should have fewer sceptics with regard to the virtue of remedies. In a third case the patient, a female set. 23, of marked strumous diathesis, all whose family were consumptive, was treated for more than eighteen months with a great variety of remedies, iron + quinine, strychnia, hark + soda, tannin, colchicum in full doses, aconite, tr. ferri mur. rtLx, Stis horis, with occasional blisters, leeches, and various sedative collyria, but without permanent relief; — even two or three months of coun- try air failed. She was then admitted into the Charing Cross Hospital, where she took bark and iron, and had the eyes repeatedly vaporized with bisulphide of carbon. This appeared to cure 5 I saw her some good while after she had left the hospital without any trace of the photophobia, which had been very great, but with a very opaque right cornea. As her circum- stances were tolerably good, and she had had the fullest ti'ial of internal remedies, it seems fair to ascribe the cure rather to the bisulphide than to the rest and nursing of the hospital. The following case, though not identical with the foregoing, has much in common, and is of practical interest. No. 91. — W. 0., £8t. 38, m., ad. Jane 18th. Suffering with his eyes for seven months ; for the first three or four he was at Moorfields, during the rest of the time he has been under the care of an eminent ophthalmic sur- geon. He had been treated since April 26th with an issue in the temple, liquor cinchon., bark -(- soda, + colchicum, pot. iod., opii gr. ^ ter die, ungt. hydr. c. opio, hydr. c. creta gr. iij ter die, besides leeches on three occasions. He was still, however, in a very suffering state when he came under my care, had been unable to work at his business, that of a carpenter, for seven weeks. The right eye could not bear the light, but appeared healthy. The left eye was in a state of marked conjunctivitis and sclerotitis, with great lachrymation, the cornea was cloudy and the iris muddy. There was great intolerance of light, so that he was obliged to hold a kerchief to the eye, though vision was lost. The globe of this eye was very tender. He had pain at the forehead and back of head. When lying down he was easier. Urine natural. B. costive. P. exceedingly weak and soft. T. quite natural.

It was therefore clear that it was useless for me to attempt to deal with it purely as a tissue inflammation. Whatever hope there might be of success must lie in endeavouring to improve the general condition of the ner- vous system, which was evidently depressed, and in calming the local hyper- gesthesia. If this could be accomplished the inflammatory phenomena might be expected to yield also. I ordered him quinse disulphat. gr. v fe.r die, and extr. bellad. gr. ^ ter die.

By August 21st THROAT DYSESTHESIA. 193 he was well enough to be discharged, though he had passed through an attack of diarrhoeal disorder. This case was treated on the principle of having re- gard to the pathological condition rather than to the local phenomena, and it may fairly be said that the result was satisfactory. The case proves, if proof be needed, that some inflammations are dependent upon nerve debility. Retinal Ansesthesia. This is a much rarer affection than its converse. It seems, how- ever, to constitute the disorder termed nyctalopia, which appears to be chiefly produced by debilitating agencies, and the neurotic charac- ter of which is further affirmed by its nocturnal occurrence. Rom- berg mentions cold, scurvy, malaria, self- abuse, and the exclusive use of coarse vegetable food as ascertained causes. It occurs, accord- ing to Ruete, in Russia, extensively among the poor in Lent. In an epidemic referred to by Mackenzie, fatigue and inhabiting small dark rooms seemed to give rise to the disorder. A residence on board ship is thought by Dr. Mackenzie to conduce to the disease. A suc- cession of blisters to the temples is recommended by Bampfield except in cases depending on scurvy. Cold bathing of the eyes, and quinine, with good food, will probably be advantageous in most cases CHAPTER XXIII. THROAT DYSiESTHESIA. This affection is a neuralgia differing in no respect essentially from the same disorder in other parts. It is certainly, at least in its well-marked forms, of rarer occurrence. From the peculiar sus- ceptibility of the throat a dyssesthesia of this part produces consider- able distress. Patients complain of feeling as if they should be ckoked, and the sense of impending suffocation is sometimes very urgent, of dysphagia, of a sense of heat, dryness and burning. The throat on inspection is found either normal, or but slightly inflamed, and the nervous distress is out of all proportion to the visible alter- ation, if there is any. The patients are mostly females, but the affection is quite unconnected with hysteria, in so far as that term is intended to imply a tendency to simulate or exaggerate disease. Where a rheumatic element can be discerned, pot. iod. or ammon. muriat. should be given, generally with bark or ammonia on account of the existing debility. If the neuralgia appear to be simple, qui- nine and iron, with ol. morrh., and sometimes arsenic steadily admin- istered, will effect a cure. For some illustrative cases, I refer to the 13 194 LINGUAL NEURALGIA. Med. Times and Craz.., May 2, 1863. The following is of tlie same character. No. 92. — E. G., f., set. 36, married, ad. Nov. 5tlj, ailing three years, ill one month. Complains of pain in neck and head, of a sensation of swelling in throat and tongue ; wakes np at night with palpitation of heart, and a sense of being very ill, attended with choking. From 8 to 12 P.M. a feel- ing comes over her as if she could hardly keep life in her ; it seems to pro- ceed from the left hypochondrium, causes palpitation, and takes away her speech. Throat is not at all sore. Has no dyspepsia Is weakly. Heart's action a little excited. When first attacked she was purple all over, and seemed to be dying ; had then been up three nights nursing. Brandy relieves her. Ordered F. + Q. citrat. gr. x + tr. nucis vom. Ti^xij + aq. §j ter die, and subsequently ol. morrh. On this treatment she has improved in a very marked manner. Dec. 3d, she was better a great deal. Jan. 11th, has been up at night nursing a sick child ; disorder relapsing. A lady recently under my care suifered most severely with this disorder ; her distress was so great she felt as if she should lose her reason. At night she was much worse ; could get no sleep in spite of several doses of chlorodyne. She had had the affection on and off for a long time ; when it ceased, which it did at intervals, she got well immediately. Bromide of ammonium and pot. iodid. were beneficial. Dr. L. Tiirck' seems to have noticed this affection, which he desig- nates as neuralgia and hypereesthesia of the throat. He states that the pain is increased by continued talking or singing, which I should think very probable. The treatment he employs consists in resec- tion of the gustatory nerve and cauterization with solid nitrate of silver. CHAPTER XXIV. LINGUAL NEURALGIA. This is a very severe and intractable variety of nerve disorder, at least in bad cases, far more so than the preceding. I have termed it a neuralgia, and believe that it is such essentially. There is, however, in well-marked instances more or less of morbid alteration of the mucous membrane. The surface appears over-red, insuffi- ciently covered with epithelium, as it were denuded in patches, between which are others of whity coating. The edges are often indented, and there may be some appearance of ulceration, but this is only exceptionally j)resent, and is certainly not of the essence of the disorder. The distress from the sore or burning sensation is very great, and the patients are apt to have a morose, unhappy look. The disorder is remarkably persistent ; in one of my cases it had con- tinued twelve, and in another six years. Of five cases, three were 1 " Wien. Allg. Med. Zeit.," vii. ix. 1862, LINGUAL NEURALGIA. 195 females. In the way of treatment iron and quinine, arsenic, ol. morrhuge, tr. aconite have proved beneficial as internal remedies, and among these I think arsenic holds the highest place. Locally borax with glycerine affords some relief. I must acknowledge, however, that I feel far from confident, when entering on the treatment of a case of this kind, of achieving any decided success. Milder cases certainly are cured, but old standing ones are very obstinate. The cause of this is, I think, partly the high degree in which the organ is endowed with nervous susceptibility, and partly its almost continual exposure to causes of irritation. II va sans dire that the state of which I am speaking is not merely the result of bad and decayed teeth pressing against the organ. The following cases are worth recording : — No. 93.— M. C, f., set. 52, ad. May 26th. Ill one year as at present, worse the last six weeks. The disorder commenced first six years ago. The tongue at its anterior third looks red, denuded, eroded somewhat, with thin white patches on its surface. A sensation of burning rather than soreness is complained of. P. of good force. Never had any cutaneous eruption. Lotion of borax and glycerine. Liq. pot. arsenit. ttlIv ter die. June 16th. Is getting better. T. much easier. 30th, Mouth very painful, burning sen- sations in throat, slight indications of an eruption on the tongue. July 10th.

T. very pain- ful last four days. Pt. She did not attend again ; probably the relapse was not of long duration, but it marks well the obstinate character of the dis- order. No. 94.— M. S., f , get. 30, ad. Deer. 16th, 1861. A large, finedooking woman, unnaturally flushed in cheeks, at present they are hot. Skin of hands cool, damp P. quick, weak. Is weakly, suckling nine months. Has headache and loses her sight at times. Has five healthy children, two dead with measles, and one with teething convulsions. She has been ill for twelve years, suffering with her tongue ; it feels sore along the edges, which are indented, but not ulcerated. Some weeks later, when she was suifering much, it was noted that there were small streaks or spots of red elevated papillse, where the mucous membrane appeared denuded ; in the intervals the surface was pale and depressed. The tip was the tenderest part. Teeth pretty sound. Digestion often imperfect. Manner morose. Urine very clear and pale, sp. gr. 1010, deposits only scaly epithelium. T. is much better some days than others. Tlie affection has been regarded as syphilitic ; she has taken hyd. bichl. and pot. iod. and pot. chloras, without benefit. She never had any cutaneous eruption. Treatment was continued, though not regularly, up to July 28th, 1862. She benefited more by liq. potas. arsen. ttlvIj — x ter die, but at the time of her taking this she became pregnant, which induced, as it had on several previous occasions, stomach derangement, and aggravated the lingual disease. I saw her again Feb. 196 LINGUAL NEURALGIA. 6th, 1863, when she had been confined fourteen days. She stated that she had suffered much with her T. all through her pregnancy, but was relieved soon after. This is the only pregnancy where this has been the case ; usu- ally the neuralgia continues a long time after. She is now again under treatment. No. 95. — J. Gr., m., ast. 33, ad. March 19th. Ill two years with tongue affection. Some spots form on one or other margin and under surface, which appear slightly depressed, and partially covered with a whity layer, detached epithelium. These were seen on several occasions during the time he remained under observation (about five months) ; they never appeared to be more than excoriations. He had had a chancre once, but there was no cica- trix to be seen on the penis. No trace of syphilis. Arsenic with tr. aconite and ferri + quin. citras was of much benefit, so that on one occasion he thought himself quite well. He soon, however, relapsed. At the time when he appeared recovered there were still traces of the whity patches remaining. In this case more than in any other there were indications of some quasi- eruptive affection like a vesicular skin disease ; but I doubt whether this was more than secondary. I think there was more sensory disorder than the small amount of visible local alteration could account for. No. 96.— W. W., m., set. 50, ad. July 27th. Ill six months. His tongue looks at anterior part of dorsum denuded, and semi-raw, with whity coating here and there, and some tendency to fissure, especially at the tip, the edges indented. He can scarcely eat anything for the soreness, which is relieved by hot water, but cold causes smarting. Never had eruption or sore throat. Had a chancre twelve years ago, and suppurating buboes thirty years ago ; no cicatrices in groins or on penis. Pain is always worse at night. About October 1st, when the tongue was feeling quite well, I observed a characteristic arcuate group of syphilitic tubercles encompassing the left commissure of the lips. Subsequently this group spread periphe- rally. Arsenic with cod-liver oil has been of material service to the tongue, so that it is kept pretty easy as long (Jan. 7th, 1864) as he continues the remedy, but on two occasions, when pot. iod. and nitric acid have been sub- stituted, he has immediately relapsed. Painting the eruption on the lips with iodine has lessened it a good deal. Jan. 25th. The state of the tongue is aggravated ; there are in the middle of the dorsum two or three fissure-like depressions with intervening induration ; the surface of the cheek is red and sore ; he feels very low and languid. The tongue is in more pain at night. Quinine gr. v + liq. pot. arsenit. Tr^x ter die. Pt. «X3. oleo. He continued this with decided benefit up to Feb. 15th, when I gave him besides Plummer's pill gr. v, o. n. March 3d. The eruption of the face had improved very much, his tongue looked much better and healthier, and felt to him nearly well ; he could eat anything. The mixture was omitted, and the oil and pill continued. 10th. Still doing well. It is doubtful in my mind whether this was a case of actual syphilitic neuralgia, ^. e., depend- ing principally on the poison of syphilis, or whether it was ordinary neural- gia occurring in a syphilitic subject. I rather incline to the latter, inasmuch as pot. iod. was injurious while arsenic was beneficial. The mercurial, however, has certainly done much good. No. 97. — E. E,., f , set. 55, had suffered since the spring of 1858 with more or less of a choking sensation, which at times came on " so fearfully" that she thought she must be choked. She described her state from this sensation as not feeling "ill exactly, but out of spirits, and fearful, as I sup- BRACHIAL NEURALGIA. 197 pose one would feel if a halter were about one's neck." Her tongue was so very sore that it was painful to eat and difficult to talk. She thought that the principal seat of the disorder lay in the tongue, which caused con- stant eflForts to swallow, and that produced the dryness in the throat. Oc- casionally she was quite free from the distressing dysaesthesia. She took quinine with decided benefit, as well as a generous diet. In the autumn of 1859 she came under my care again in a state of great depression, with a cold, pallid skin, very weak pulse, anorexia, nausea, and very distressing sense of dryness of the mouth, her tongue feeling like a piece of leather. The night was the only time when she was quite free from the distressing sensation. Tongue appeared indented, but not ulcerated. Bark + ammo- nia was given, and acidi arseniosi gr. oV ^^^ '^'*^) ^^^ ^^^ removed to the seaside. In three weeks she was almost if not quite well. In this case there appears to have been a combination of lingual and pharyngeal dysses- thesia. I have considered several times how far the condition of the tongue described above could be regarded as the result of lichenoid eruption, but I have never seen any such state of the tongue in ordinary lichen or prurigo, nor have I seen in lingual neuralgia any such eruption of the cutaneous surface, nor has the appearance of the tongue itself sufficiently warranted the supposition. In severe cases of this disorder Dr. L. Tiirck's practice of dividing the gustatory nerve might, I think, be adopted. CHAPTER XXV. BRACHIAL NEURALGIA. Romberg gives but a short notice of this form of neuralgia ; he considers it less frequent than crural, and less isolated than sciatic and facial neuralgia. Lussana and Bergson have entered fully into the subject in their prize essays published at Milan 1859, 1860, and reported fully in Schmidt's Jahrh.^ vol. 108, p. 168, and vol. 113, p. 296. Lussana describes at length the various symptoms produced by neuralgia in the several nerves proceeding from the plexus, noticing particularly the terminal painful points, the superficial, and the in- termediate painful track (via dolorosa). The superficial painful points are where a nerve is given off from its trunk, where it perforates a muscle, or runs round a cylindrical bone, and where it becomes subcutaneous. In its direction the pain may be centripetal or cen- trifugal ; in the latter case it is continuous, and without any elevation of temperature. The pain is as a rule increased by pressure, and, ex- cept in the case of the internal cutaneous nerve, by motion. With regard to the temperature of the affected parts Lussana finds it ob- jectively or subjectively increased in neuralgias of cutaneous and sensitive nerves ; objectively or subjectively lowered in neuralgias of nerves that are chiefly motor. Whenever the affected nerve is 198 BRACHIAL NEURALGIA. compound, i.e., motor as well as sensory, muscular symptoms are ob- served, which vary much in degree, but may amount to complete paralysis. If the short and long thoracic nerves are affected, the respiration may be short, laborious, and painful. Pyrexia rarely occurs except in plethoric habits ; nausea and gastric disorder may be present, or even delirium. The type is generally inter- or sub- intermittent. The diagnosis between Br. Neuralgia and Neuritis is made to turn on the greater rarity of neuritis, on the more apparent causation of the latter, on the absence of pyrexia in neuralgia, on the more continuous character of the pain in neuritis, on the absence of signs of local inflammation, and of local tenderness on pressure of the affected nerve, on the greater amount of pain in the termi- nal points in neuralgia, and in the trunk in neuritis, on the greater constancy and earlier appearance of paralysis in neuritis, on the greater severity of the muscular cramps and spasms, and on the different state of the terminal points in chronic cases, they being painful in neuralgia and anaesthetic in neuritis. In neuroma the pain extends more in a centripetal direction than it does in neural- gia. Lussana notices the existence of neuralgic pains in disease of the heart and great vessels, in disease of the lower part of the cer- vical region of the spinal cord, and of the vertebral column, in hepatic disease, in constitutional syphilis, and in lead poisoning which might be mistaken for essential brachial neuralgia. Bergson arranges brachial neuralgias more according to their causes, as traumatic, rheumatic, sympathetic, hysteric or chlorotic, saturnine, such as depend on spinal irritation, and finally the idio- pathic or essential. He rests the diagnosis of neuritis on the almost invariable previous occurrence of an injury, and on the increased size of the painful nerve, which can be detected through the skin. True chronic idiopathic neuralgia he considers to be very rare, and very refractory to treatment, while acute is much more tractable. I have records of seventeen cases in which the nerves of the hand and arm, especially the median and ulnar, were the seat of more or less severe neuralgia. As the affection has not been described so particularly in our own country, it may be worth while to record them shortly. Fifteen of them were females. The oldest patient was sixty-six, the youngest twenty. Case 1, — M. C, aet. 25, f.; ill three months with pain of right hand affect- ing all the parts supplied by the median nerve. It is worse at night, de- stroys sleep. After other treatment continued for a month had failed, I gave quinine gr. v te7' die, and subsequently gr. x ter die. Under this she was well in three weeks. Case 2. — H. 0., f., aet. 54 ; ill for a long time with a numb and sleepy feeling in her hands at times, aggravated to violent pain at night. Cured in about ten days by small doses of quinine and iron. Case. 3. — C. B., f , of mid-age; is awoke during night by a numbness or pain in the fingers of both hands, those supplied by the ulnar nerve being first affected. The morbid condition extends to the forearm. During the BRACHIAL NEURALGIA. 199 day the neuralgia ceases. Cured in five or six weeks by moderate doses of quinine + iron. Slight rigors occurred at night as the neuralgia yielded. Case 4. — M. J., f., aet. 29, four months pregnant. Ill one month with pain in hand and forearm not extending above elbow, severe at night, but felt only as a numb sensation during the day. There was marked debility. Quinine gr. xv and 5s?s in the day failed, and so did arsenic and ferri carb. ; quinse gr. ij + ferri sulph. gr. iv ter die, was now given with morphia and henbane at night, and cured in three weeks. Case 5. — E. E., f., set. 56, complains of pain in right forearm extending from fingers up to elbow, commencing in mid-finger. It is of more burning character at night, does not disturb her rest, but is very severe in morning, when she cannot move her hand to open or close it. The fingers often feel burning when she touches or holds anything, at other times are numb. Foot somewhat similarly affected. Small doses of quinine + iron, larger doses of quinine, carbonate of iron, muriate of ammonia and cod-liver oil failed to do more than to give some temporary relief. Under strychinae gr. Y2 ter die and extr. col. co. gr. v, o. n., with the continued use of ferri carb. she improved considerably, so that she was able to do needlework, whereas she had at first been unable to hold a needle. She continued this treatment five or six weeks, having had for the last fourteen days pot. iod. gr. ij ter die in addition, and was then well enough to be discharged. One galvanization appeared to be beneficial, a second rather injurious. Case 6. — J. M., f., aet. 48, suffers with bleeding haemorrhoids. Ill three months with pain in centre of right palm extending up the arm over the shoulder to the spine ; it is constant and gets worse, is increased at night. Hand is numb except the fingers and thumb; there is much burning sensa- tion in it. No sleep at night. Cured in a month by small doses of quinine + iron, and morphia at night. It was remarkable in this instance how the pain extended itself upwards like an aura, not in the track of a nerve, and how the fingers were exempted from the disorder. The affection was evi- dently peripheral. Case 7. — E. M., f., set. 47 ; ill three weeks with pain, chiefly of right mid- finger, in day-time it is numb. Left hand slightly aifected. Urine very thick. Pot. iod., liq. pot. arsen. and liq. pot. for a week were of no avail, quinine in gr. xv and xx dose daily was more beneficial, but recovery took place under quinine + iron + liq. opii sed. in small doses with henbane at night. Some pruritus pudendi occurred during the last few weeks of treat- ment, and was much benefited by a borax and opium lotion. Case 8. — J. T., f., aet. 66. Ill more than six months. Is quite well except in her arms, which get stiff and numb, and ache, and are very cold. She suffers thus most at night. She took ferro-citrate of quinine gr x -f- tr. nucis vomicse ttlx + aq. 5j ter die, and used locally lin. camph. co. In six weeks she was nearly well. Case 9. — S. K., f.^ aet. 40. Ill more than a year. Has pains in hands, extending up arms to shoulders, giddiness and general weakness. Most pain in right arm. Pain shifts from hands occasionally to the left side. With pot. iod + citrate of iron and quinine, she recovered in about three months. Case 10. — E. L., f., aet. 46. Ill fourteen days. Cat. ceased three years. Some rheumatic symptoms lately. She took at first pot. iod. with alkali and eolchicum with benefit for a week, her head being relieved; but she complained of her hands being attacked with numbness and cramp in the morning about 5 A.M., which continued in fits of ten minutes duration off 200 BRACHIAL NEURALGIA. and on till noon. A week later the pain came on earlier in the middle of the night, and was severe. With quinine and iron in moderate doses she im- proved, but did not recover. Probably rest and good food were essential as affording a basis for medical treatment. In this respect the disadvan- tages of external hospital patients can hardly be exaggerated. Success with them is a real test of the efficacy of drugs. Case 11.' — E. B., m., set. 65. Ill three or four days. Stout, healthy looking. Has lost the use of right hand, can hardly grasp at all with it or use a knife or pen. The parts supplied by the median nerve are numb, but never in pain. Feels some stiffness up to the elbow. The affection came on suddenly. No pain in head, no giddiness. Not subject to rheumatism. Skin warm. Glands in axilla not enlarged. He took for a week hydr. bichl. gr. } + pot. nitrat. gr. x + inf. gent. co. ^j (er die with slight benefit. Afterwards he had citrate of iron and quinine gr. 8 ter die., and was well in a month. Case 12. — C. G., m., set. 20. Ill one week with pain in left arm, from elbow to tips of fingers ; worse at night, relieved by heat. With gr. xij of quinine daily he was quickly well. Case 13. — C. R., f., aet. 40. Ill three weeks with pains in arms and hands ; after much exertion her fingers get quite straightened so that she cannot bend them at all, she then feels " awful" pains in fingers extending up to shoulders. The pain is a great deal worse at night, is a sort of ting- ling and numbing pain. Can hardly dress herself in the morning. Left arm but little affected. Skin warm. Urine pale. Pulse not weak. Small doses of quinine + iron and pot. iod. were of no avail ; she complained eleven days after admission, that if she had any hard work during the day her hand at night got quite stiff, and was in unbearable pain after she had slept about two hours; while if she had a quiet day she suffered only numbing and tingling sensations at night. The fingers got numb if she tried to write or sew. She suffered in exactly the same way eleven or twelve years ago. She was con- siderably improved by full doses of quinine gr. 20 — 30 in the day. An interlude of dyspepsia then occurred, after the relief of which she took ferri carb. gr. 20 te7' die, and was nearly well at her last visit. The effect of exertion in aggravating the disorder was very apparent in this case. Case 14. — A. R., f., aet. 43. Ill seven days, was attacked in sleep all of a sudden, pain came on in the left shoulder, ran down the arm, and set- tled in the hand, which feels very powerless ; the two inner fingers are much more numb than the others, but all are much affected. The pain in the hand keeps her awake at night, being worse then ; it shoots down from the elbow. Hand sometimes very cold, at others hot, when hot the pain is in- creased. Urine clear. Aspect pallid. P. weak. The pain quite ceased under full doses of quinine, gr. xl — 1 a day with ol. morrh., and the numb- ness also diminished, but the hand remained almost completely paralyzed with scarcely the least movement of flexion or extension. The quinine alone seemed only to weaken her memory and sight a little ; when ferri sulph. was added, she became nearly blind and deaf After this she was ordered strych- nise gr. 2^^ — ^g- with tr. cinch., under which she regained some motor power, but in spite of galvanizing both with the interrupted and continuous current (she wore Pulvermacher's chain for some time) and a month in the country there was still very little power over the hand, when I last saw her after three months' treatment. Case 15. — A. L., f., set. 47; ill at first for six weeks with sore throat BRACHIAL NEURALGIA. 201 and debility, got much better. At end of three months began to complain of agonizing pain extending from shoulder to wrist, and to the finger ends, continuing day and night, destroying all rest, and extending up the side of neck. No difference in appearance or temperature of affected parts. P. of good force, rather frequent. Of large make. Feels very weak, but other- wise well. Quinine in daily dose of gr. 20 to 28 failed to benefit, as well as extr. belladou. gr. ^ 2dis horis, and liq. pot. arson. n\,v ter die. Pot. iod. gr. V — vij ier die, with two opiate subcutaneous injections was of some service, but most benefit was obtained by the local application of tr. aconite undiluted with arsenic internally, under the use of which the arm became quite well. Just after this, the aconite having been continued about one month, and the arsenic five weeks, an eruption appeared on the upper arm attended with fearful itching and much heat and redness. The aconite was replaced by a strong lead lotion, and the arsenic continued. Three days later erysipelas had markedly developed itself over most of the arm and shoulder, attended with swelling and papular eruption, and pinching and burning pain in the part. She felt shivery. P. excited and feeble. Bark and ammonia were ordered, and the arsenic omitted. In four days all the redness had subsided, the swelling continued with much pain about the arm of scalding character. Much thirst. In ten to fourteen days she was well. In this case aconite and arsenic appeared to be the most effectual remedies. I can scarcely think the aconite had anything to do with producing the erysipelatoid inflammation, as it had been used fully three weeks without any such result. I have, however, known aconite to cause cutaneous irritation. If this cause be put aside, I see no other view to take than that as the cerebro-spinal nerve disorder yielded the vaso-motor nerves became implicated, and this in the way of paralysis. There does not seem in this case to have been any musculo-motor nerve paralysis, which was so marked in No. 14. In a case I saw only once the patient, a female, aet. 45, suffered •with nocturnal burning, throbbing, and painful sensation in hands and arms extending up to the shoulders with numbness of the fingers. The urine was clear, she had no indigestion. Case 16. — E. G- , f., set. 26; ill two months ago with scarlet fever, on making any exertion experiences a pain in chest, and loses sensation and power in left arm. P. 96, weak. She took strychnia and iron, and was nearly well in fourteen days. Case 17.— S H., f., at. 34, ad. May 19th, ill five weeks. Her right hand " goes dead" three or four times a day, it is constantly weak so that she cannot hold things with it, and she has constant pain and tenderness at the styloid process of the radius ; no swelling of the wrist. T. whity and in- dented. B. costive. Urine rather dark. Has lumbar pain. Is weak and languid. She was not benefited by small doses of quinine and pot. iod., became worse with exceeding pain about the wrist and up the arm ; a blister had caused much irritation. The hand was so cold one night (May 28th), that she was obliged to put it for relief into hot water. There was some diarrhoea and nausea, and she felt extremely depressed and languid. The quinine was increased to 9i in the day and the bowels quieted with opium and chloric ether. June 2d. A great deal better ; the other fingers are comfortable, but she has much pain in the index and thumb. While the blister was open she was free from pain in the styloid process, now it has returned to that part, and to the adjacent articulation of the thumb. The quinine was increased to gr. viij ter die, and by the end of June she was convalescent and went to the country. 202 BRACHIAL NEURALGIA. The above histories are sufficient to prove that brachial neuralgia is not, at least in this country, a very rare affection ; it is rather curious that unintentionally I have recorded just as many cases of this disorder as of sciatica. The two seem to be essentially similar in their nature, relation to rheumatism, causes, and treatment. A rheumatic element appears, however, to be much less frequent in brachial than in sciatic neuralgia, and in correspondence with this pot. iod. and arsenic are found to be less efficacious. The influence of debility in predisposing to and maintaining the disorder is very decided. Besides this, however, we must assume some special agent to be affecting the nervous system injuriously. What that is cannot be precisely stated, but it seems to me that we shall not err greatly if we suppose some general miasmatous influence, widely dispersed, and varying much in its potency at different periods, to be the efficient motor of the phenomena. There seems to be some sound reason for believing that neuralgic and epidemic catarrhal (influenzal) disorders are rather closely correlated in their origin, the cause of the latter giving rise also to the former. Mr. Norris, of Petherton, and Mr. Ewens, of Blandford, have recently stated' their experience as to the occurrence of sequelge of hemicrania, and intermittent cephalalgia in connection with influenza. Hjaltelin^ says that influenza in Iceland was followed by various neuralgic pains, especially lumbago, otalgia, odontalgia, facial and intercostal neuralgia and hemicrania. Similar observations have been made long ago as already stated by others. Several points of the above histories illustrate the neuralgic habitudes of the disorder. The nocturnal aggravation of the pain ; its remission or absence by day ; the intimate relation between it and numbness so that the latter seems to be a less degree of the same condition ; the coexistence in some instances of motor disorder ; the prevalence of general debility ; the absence of self-limitation are family features of neuralgia. The results of the treatment above detailed seem to me to show pretty conclusively that the malady was not depending on any remote cause of irritation, as decayed teeth, worms, intestinal accumulations, &c. ; nor on gouty poison or dyspepsia. These, how- ever, are very possible causes, and we should be prepared to meet with them. The influence of heart-disease in producing a certain form of brachial neuralgia should also be remembered. The cases illustrate sufficiently the treatment which should be pursued. One main point is to improve the general tone and strength. If this be effectually accomplished, there will not generally be much more required. Good air and food, and the usual tonics with occasionally a nightly sedative are the most reliable means. In some instances ammonia, valerian, and arnica, with nitrate of silver prove more beneficial than quinine. In local applications I have not much faith, but they may sometimes, as in No. 15, afford much benefit. The interrupted current will I think chiefly be found useful where there is motor paralysis ; I am ' "Med. Times and Gaz.," April 11, 1853. 2 "Edin. Med. Journ.," Feb. 1863. BRACHIAL NEURALGIA. 203 sure that it should be used cautiously to weak and hyperaesthetic nerves lest it aggravate rather than relieve the pain, Becquerel,^ however, maintains that an induced current passed through a nerve in its long axis will always cure neuralgia if the stream is sufficiently strong, and the intermissions are very rapid. I confess I should not like to be the patient so treated. With regard to the continuous current it might, I think, be serviceable as a means of procuring temporary relief, but it is a very troublesome means to use (I speak of Pulvermacher's chain), and would be of little real avail unless the morbid tendency of the general system were amended by tonic treatment. Dr. Radcliffe has recently praised the use of the hypo- phosphites in neuralgia, together with cod-liver oil and fatty food, viewing the disease from a chemical stand-point. I have not found any special advantage from the hypophosphite of iron and quinine in a few instances of various disorders in which I have tried it, and I certainly should not be disposed to rely on the acid alone to the exclusion of the two bases whose efficacy is so well proved. As an occasional sedative I am as much disposed to rely on chlorodyne as on anything else. A patient of mine told me she had cured her- self with this of a sciatica which had proved refractory to orthodox medical measures. I must say, I should never use willingly any preparation whose composition was kept secret. The following his- tory seems properly to find its place here as it refers certainly to a peripheral neurosis, and not to a central affection. The disorder was probably of the same nature as neuralgia, but, inasmuch as it was located in a mainly muscular nerve, it produced rather paralysis than pain. There was, however, very marked loss of sensation, which is often as much a part of neuralgic disorder as pain. Case 18. — G-. W., ast. 40, ad. Nov. 11th; ill fourteen days. Has lost the use of his right arm, so that he cannot raise it from the shoulder-joint and abduct it by the action of the deltoid ; he can move the forearm, but not so well as the other; has had great pain about the insertion of the deltoid, which came on in the course of the night, and has been replaced by numbness. The angesthesia does not extend quite to the elbow. Is not subject to rheu- matism. Functions generally in good order. Does not feel weak. Works in a damp place in a brewery. Dec. 20th. Right deltoid much wasted, un- excitable by galvanic current, skin covering it also very numb; the adjacent muscles and integuments are quite lively and sensitive. Whichever pole is applied to the highest part of the arm while the current (interrupted) is passing he feels the shocks there, not in the lower. But if I place the poles opposite each other on either side of the deltoid, he feels the shocks in both. He finds the arm stiifest in cold weather, and he suffers more pain then in it. The chief pain is a little below the seat of numbness. Jan 7th. Del- toid much wasted, remains insensible to the strongest current, which has been used almost daily. On one occasion the current was sent directly through the muscle by needles passed through the skin. No good effect ensued, but he was unable to bear nearly so strong a current as before. Ife ' L'Union Med,, Nos. i. and iv., 1861. 204 SCIATICA. is very observable that the cold air produces "gooseflesh" all over both upper arms and shoulders when he is stripped, except over the paralyzed deltoid. Some weeks later the interrupted current had precisely the same effect, the anaesthetic skin remaining quite smooth, while the sensitive con- tracted. Feb. 4th. I have passed a continuous current from a 6-cell battery through needles stuck into the muscle, no muscular motion nor any sensa- tion was produced while the current was passing, but on interrupting it the muscle contracted. The deltoid has shrunk and wasted much since I last saw him. He was now directed to wear a small Pulvermacher's chain on the affected part. In three weeks there was no improvement ; the deltoid and infra- spinatus muscles were quite irresponsive to faradization, the skin over them still numb. March 12th. Slight improvement. April 16th. Is recovering more use of arm, and the numbness diminishes. By about the middle of September, up to within a month of which he wore the chain, he had quite recovered save a little numbness in the skin over the insertion of the deltoid. Medicine had a fair trial in this case, and appeared ineffectual. Pot. iod. in gr. v doses ter die, pil. hydr. c. opio to salivation, sulphuret of potassium baths, strychnia carried up to gr. \ ter die, and ammon. murias failed to produce decided amelioration. The strychnia was certainly continued at the rate of gr. -^^ ter die, during a good part of the time during which he was wearing the chain, but as it had been fairly tried before without benefit I think it cannot lay claim to the improvement, which was due either to the continuous current or to the vis med. natures. The chain is no favorite with me; it is a troublesome and rather painful remedy, but I think there is much ground for regarding it as the really effectual agent in this case. Paralyses such as the one above, described are much more apt to remain as chronic and incurable affections than to disappear of themselves. The pathology of the above case is obscure, the most probable view is that the disorder was essentially similar to neuralgia of sensory nerves, but it remains unexplained ■why it was so refractory to treatment. It yields, however, in this respect to Case 14, which was not benefited by the chain, but which in most respects quite corresponds to the picture of neuralgia. It is quite possible and probable that in certain cases the molecular change which conditionates neuralgia may pass on to larger and more complete alteration, even to organic lesion. CHAPTER XXVI. SCIATICA. Cases. — (1.) G-. N., set. 56, m., ill nine months with severe sciatica; cured by cinchonine and iron with ungt. veratriae.

Ill fourteen days with left sciatica, nervous debility very marked. Hypodermic morphia injection gave no relief, nor did pot. iod., nor colchicum, nor ferri carb., nor croton oil aperient at night, but under the steady use of arsenic gr. gV ^^'* ^'^^ ^^ recovered. The least exertion caused extreme perspiration. (11.) L. C, f., set. 52. Ill fourteen days with left sciatica, marked debility, and vaso-motor nerve disorder. Has flushes of heat succeeded by perspiration three or four times a day; "fingers die now and then, turn numb and cold as marble, and the nails become black." Under F. + Q. citr. and aconite lotion she benefited very much. The motor power of the limb was impaired somewhat. The neuralgia afiected also the right side of the face. Treatment= thirty-nine days. (12.) T. D., m., aet. 45. Ill four months with right sciatica, making him walk lame. Is getting worse, very weak and emaciating. Most pain over exit of sciatic nerve.

(15.) E. W., f., set. 49. Ill two or three months with left sciatica, affected limb colder than the other. Not benefited by pot. iod. + bark, with mor- phia blister, but materially by quinine + iron. The neuralgia showed a tendency to affect the head. (16.) C. P., set. 38, f. Ill six months with left sciatica. A morphia blister, pot. iod. + vin. colch., iron + quinine, and ferri carb. were of no avail. Quinine gr. 20 in the day was of material use, but arsenious acid appeared to be the most effectual remedy. Liq. opii sedat. was injected several tiines with temporary relief. Treatment=six months. (17.) M. M., m., set. 63. On ad. had had sciatica four to five months since a wetting while perspiring; health generally perfect ; pain increased by changes of weather. Left leg/ee/.s- very cold, but the actual temperature of both is about the same, 90° F. Pain extended quite down to ankle, was replaced to some extent by numbness in the course of the treatment. He remained in the hospital seven weeks, had quinine, arsenic, iron, pot. iod., croton oil, subcutaneous opiate injections, and morphia blisters, but did not make very satisfactory progress. The above cases show pretty clearly that sciatica is for the most part essentially a neuralgic affection quite similar to neuralgia in any other situation. The proportion of males to females in my cases is considerable, 11 : 6, a circumstance which, if not accidental, may be explained by the greater exposure of the male sex to chills, &c. The impairment of motor power which often occurs has been well noticed by Romberg, and is certainly almost as noteworthy a feature as the pain. It shows that the morbid action is not con- fined to the sensory nerves, but affects the motor in juxtaposition with them. Of the nature of this morbid action we can say little more than that it appears to be identical with that which produces neuralgia in other situations, that except perhaps in recent rheumatic cases it is not inflammatory, and especially that it has usually a positive relation to debility, and will not yield permanently until at least some degree of strength and vigour is restored. Dr. Rad- cliffe's suggestion that owing to impaired nutrition some breach occurs in the oleaginous investment (white substance of Schwann) of the axis cylinder is I think probable, and at any rate may serve provisionally as a representation to our minds of the state of the parts concerned. Romberg admits the occurrence of a spontaneous cure in connec- tion with critical symptoms, as diarrhoea, menstrual, lochial, or hae- morrhoidal discharges. I do not wish to question the possibility of this ; but according to my own experience the continuance of any discharges of this kind is much more likely to perpetuate than to cure a sciatica. Neuralgic disorder is occasionally met with which affects more the superficial nerves of the lower limb than the deep- seated sciatic trunk. It is essentially similar to the more common affection. The diagnosis of sciatica does not generally present any SCIATICA. 207 material difficulty. Pain extending down the posterior aspect of the limb in the course of the nerve, especially felt, and increased by pressure between the ischiatic tuberosity and the great trochanter, but not aggravated materially by the movements of the joint, or by pressure of the articular surfaces together, can scarcely be due to other cause than sciatica. The most important point in refractory cases especially occurring in the female sex is to determine whether or not the pain is dependent on any intra-pelvic, or other organic disease. Churchill mentions a case {Diseases of Women, p. 253) where an ulcerated uterine cancer produced no pain except in the whole course of the sciatic nerve. In such cases there will however almost always be other symptoms, such as discharge, or hemorrhage, which will indicate the true nature of the disease. It is most pro- bable that the pain from cancer uteri is of reflex character, and not occasioned by direct irritation of the nerve. This I conclude partly because the uterus is too remote from the sciatic nerve, and partly because fibrous and ovarian growths which are more likely to press on the nerve do not have the same effect. Trousseau^ declares that sciatica is often dependent on disease of the vertebral column, kid- neys, testes, uterus, and rectum, and states that Chomel went so far as to disbelieve in the existence of essential sciatica. He mentions a case where it occurred in a young female after delivery in conse- quence of a slow inflammation of the sacro-iliac symphysis ending in abscess. The condition here was probably one of neuritis. Though I have the highest respect for Trousseau's opinion I must say that my experience does not confirm his and Chomel's view as to the fre- quency of the remote origin of sciatica. The disease in some cases has a rheumatic character, the urine being lateritious and acid, a certain amount of pyrexia being present, and the strength not much impaired. Here potass, iod. and vin. colch. with alkali are curative, but the iodide should be given in pretty large doses, gr. vij — x, ter die. In the majority of instances, however, there is more or less marked debility, the urine is free and pale, the tongue clean, and tonics are evidently indicated. Among these I am inclined to rate arsenic rather highly, as it has served me well in cases which would scarcely I think have recovered with- out. I am rather partial to the simple solution in distilled water, which easily dissolves gr. j'^ per Ij. As a means of improving the general nutrition, as well as that of the afi'ected nerve, it will be well to administer ol. morrh. in all cases bearing the stamp of de- bility. I am aware that some physicians have found repeated small doses of croton oil of great efficacy, but it has not occurred to me to meet with such. The remedy should however be borne in mind in dealing with refractory disease of this kind. I say of this kind, for it is by no means useful only in sciatica, but also in other neu- ralgias. This goes far to disprove the view of the mechanical cau- 1 "Clinique Europeenae," No. iii., 1859. 208 SCIATICA. sation of sciatica, viz., that it is produced by the pressure of scy- balous masses in the lower bowel. This mayi occasionally be the case, but certainly it is not common, and on the other hand con- stipation very often produces no sciatica. I remember an old man in whom by reason of a large epithelial cancer of the lower rectum the feces concreted above into masses about as large, and almost as hard as a walnut, which enemata would bring away; yet he had no sciatica. I am rather inclined to look upon croton oil as acting in certain cases as a specific stimulant to the nervous system. Cases no doubt occur where local bloodletting is necessary, but I can scarcely believe that venesection can be requisite as Romberg states. If this is ever the case, it must be when there exists con- siderable pyrexial disturbance of a sthenic character, and this might be always allayed I should think by other means. 01. terebinth, has maintained for some considerable time its reputation as a remedy for sciatica. I have used it but little, chiefly because the state of the general system has seemed to require more decided tonics. I consider it most appropriate to those conditions where there is no marked debility, or indication of recent rheumatism, or of or- ganic disease. Hypodermic opiate injection gives considerable temporary relief in some cases ; it is apt, however, to cause much distressing nausea and sickness. It is scarcely desirable to use it except where the suffering is severe. As a local application if the pain be severe, and the limb intolerant of pressure, I think aconite lotion is the best. If the pain be more gnawing and wearying and tenderness be not marked, chloroform and opium liniment is pre- ferable. Veratria ointment and belladonna are appropriate to cases where the tenderness is less than in those requiring aconite. Some physicians have much confidence in " firing," I do not mean using the actual cautery, but iron heated by being dipped in boiling- water. Dr. Graves indeed states that in very obstinate cases the actual cautery applied to five or six spots along the course of the painful nerve is the means most to be relied on. I should consider this, however, quite a " dernier ressort," and certainly not to be em- ployed unless I was well satisfied of the absence of organic disease as well as of general debility. It cannot be too clearly kept in mind that as long as the latter continues no real improvement can be effected. Dr. Fuller speaks highly of acupuncturation, and there is no doubt of its frequent efficacy in this and other neuralgic affec- tions, although I am not convinced that its virtue depends on the evacuation of effused fluid. Dr. Althaus has found faradization of the affected nerve effectual in sciatica, I can quite believe that this is the case, but it is requisite in using the interrupted current to take care, (1) that the condition is not one of inflammation, and (2) that the strength of the current is not too considerable. I am satisfied that the pain may be aggravated if this caution is disre- garded. Torri^ relates ten cases of sciatica cured by weak con- ' "Gazz. Med. Ital. Toscan." 1857, Nos. xlii., xliii. SCIATICA. 209 tinuous currents kept up uninterruptedly for two days. The posi- tive pole was applied to the leg, the negative to the thigh, the epi- dermis having been previously removed at each spot, and a sponge moistened with saline solution placed in contact with the cutis. The pain of this proceeding we can aver must have been severe, and we are not surprised to read that the skin in contact with the zinc always became gangrenous and required some time to heal. The pain may have been lessened by the half grain of morphia which was placed upon the denuded cutis. A case is recorded by Hooker' in which division of the popliteal nerve was successfully resorted to for severe neuralgia of the leg. Jobert de Lamballe^ has also di- vided the sciatic (and crural) nerves in a case of great severity, but though much relief was afforded the patient died from sloughing of the skin over the sacrum and pyaemia. He renounces this ope- ration in favour of the actual cautery. Finco^ reports that he has treated 48 cases of sciatica by cauterizing the ear. In 30 the ope- ration was quite successful, in 10 partially so, in 8 it failed. The failure is ascribed by F. to the presence of various complications. In almost all his cases vigorous antiphlogistic treatment was em- ployed before the cauterization, and in some its effect was aided by mercurial or belladonna ointment. The operation had to be repeated only in 3 cases. Duchenne* rejects the use of the cautery, but thinks that the interrupted current may be employed in its stead. He prefers, however, to act loco dolenti, using dry conductors. Crural Neuralgia. My experience accords with Romberg's that this is a much rarer affection than sciatica, but that in essential points it closely resem- bles it. Direct irritation of the nerve from a loaded intestine or some similar cause may give rise to it, but less frequently I think than the obscure influences which so commonly produce nerve dis- order. The possibility of neuralgia and impaired motor power of the thigh being dependent on the existence of obturator hernia should be borne in mind, and if any symptoms of intestinal obstruc- tion are observed, an operation should be at once performed. The following case is an example of non- organic crurai neuralgia. Case 18. — Mrs. F., set 65, seen June 14th. A frequent sufferer from neuralgia affecting various parts. Was attacked yesterday in afternoon with intense pain affecting both lower limbs from the hips to the ankles and heels. The pain was diffused over the front and exterior of the limbs, and was attended with a sense of powerlessness. She kept rubbing the parts constantly in hope of relief. Functions in order. The pain continued severely from 5 P. M. to 1 A. M., remitted then somewhat, but returned « "Lancet," Oct. 1, 1859. 2 " L'Union M^d.," No. Ixxvii., 1859. * " Gaz.

Up to noon of 14th she had no sleep in spite of itl 120 of liq. morph. bimecon. given since the previous evening. A liniment of chloroform, belladonna, and opium gave no relief. Quinine given to moderate cinchonism subdued the pain ; on 15th she was quite free. Some slight nocturnal fever occurred as the neuralgia yielded. For some weeks before her attack her nervous system had been much deranged in consequence as she thought of a thunderstorm. In another case a delicate boy, set. 9, had agonizing pain in his feet occurring in paroxysms succeeded by copious perspirations. Pot. iod. 4- pot. bicarb, was of no benefit, but with citrate of iron and quinine he soon got well. CHAPTER XXVII. ANGINA PECTORIS. My noticing this disorder among the functional diseases of the nervous system will show that I consider it to be au fond a neu- ralgia. Dr. Watson objects to this view :* (1) because the paroxysm is excited by such causes as are especially calculated to disturb the natural action of the heart, bodily exertion, and mental emotion ; and (2) because the disease is so very frequently and suddenly fatal, which is not the character of mere neuralgic diseases in general. To this it may be replied that exertion and mental emotion are causes which do very much increase and even induce various neuralgise. A gentleman about whom I was lately consulted suifered with an obstinate neuralgia of the side of the chest, which subsided on his remaining perfectly still, but was immediately reproduced by moving about. Neuralgia in other parts is not fatal just because the func- tion of the organ is not essential to life. No one can be surprised that " tic douloureux," or sciatica, or the like should not endanger life. Dr. Stokes,^ from his examination of the subject, concludes that the special group of symptoms described as angina pectoris is but the occurrence in a defined manner of some of the symptoms connected with a weakened heart. Obstruction of the coronary arteries he considers as no necessary condition. According to this view a weakened state of the heart is essential. I cannot agree with this, as I have certainly had patients under my care with con- siderably weakened hearts who presented none of the symptoms of angina pectoris. And again I can adduce one if not two cases where after death from this affection the heart was found in a toler- • "Lectures," vol. ii. p. 259. ^ "Dis. of Heart and Aorta," p. 487. ANGINA PECTORIS. 211 ably healthy state. Something there must be I think beyond simple weakening of the organ to account for the peculiar phenomena of the disease. It is however quite reasonable to believe that a variety of morbid changes may predispose to it, and indeed this seems to be the fair inference from the observations which have been collected by Dr. Forbes. This opinion seems to be that entertained by Dr. Copland. Dr. Latham regards the disease as spasm of the heart, insisting on its analogy to cramp in the voluntary and involuntary muscles, and on the efficacy of opium in relieving the distress. Lussana adopts the same view, citing an observation of Morgagni's who found at an autopsy the heart " durum valde et robustum," and another one of Carron d'Annecy where the heart was very much contracted. He thinks it demonstrated that the heart's muscular tissue during the attack is in a state of cramp like contraction, and remarks that the character of the pulse as generally observed is in conformity with this view, being brief, small, hard, and often accele- rated. V. Schmidt's Jahrb., vol. 108, p. 312. Dr. Walshe' says that " angina pectoris seems to be constituted by spasm of the heart, and neuralgic pain," and doubts whether it ever occurs without some kind of structural change in the organ. It may be remarked that a cramp-like condition of the heart's tissue would quite as much interfere with its functional action as a paralytic state. It is quite as essential for the heart to relax duly to admit blood into its cavities, as it is that it should contract and expel it. The pallid face, sunken features, and feeling of impending dissolution may quite be ac- counted for on the view held by Latham. Lussana states, what seems scarcely in accordance with general experience, that after the attack the continued contraction of the muscular fibres is succeeded hj languor, exhaustion of irritability, and finally paralysis, to which even the pain itself contributes. Therefore the heart of anginose patients falls after the attacks into a condition of collapse, and the circulation is languid and feeble, so much so in some cases that the pulse and the heart's impulse become imperceptible, and the patient at last becomes faint and dies quietly. Dr. Stokes, on the contrary, speaks of the pulse during the attack as being almost imperceptible, and says nothing of any subsequent syncopal state. Morgagni and Carron found in two patients who died during the attack the right cavities completely empty, and the left ventricle nearly so, the pul- monary artery and the vena cava on the contrary distended with blood, which was black and quite fiuid. In patients who had died in the intervals of the attacks coagulated or fluid blood was found in larger or smaller quantity in the cavities. Lussana regards the latter as indicating paralysis, the former tetanus of the Ijeart. He thiuks generally that the blood of anginose patients is but slightly coagulable ; in one of my own cases the fluidity of the blood was i " Dis. of Lungs and Heart," p. 434. 212 ANGINA PECTORIS. remarkable. His final conclusions are that the disease may be dynamic or organic ; but that for the most part it is the latter, being in fact produced by mechanical irritation of the cardiac plexus resulting from calcareous degeneration of the coronary arteries of the heart, or some similar cause. It is thus invariably a neuralgia, whose sole and constant seat is the cardiac plexus. The three following fatal cases in which autopsies were made came under my own observation. No. 98. — J. 0., set. 39, m. Seen Dec. 15fch. Always had a rosy colour. Never bad rheumatic fever, but had pain in left temple, stopped by local applications. Has been ailing several months. About nine weeks ago had the first attack of pain in his cheat, " it turned his face white/' Up to Nov. 16th, when he was admitted as in-patient, he had the attack once in two or three days. While in hospital he had a short hacking cough, pain in epigastrium extending up to the throat increased by walking, which also brought on palpitation. Heart's action regular, loud diastolic bruit at base and apex, cardiac dulness not increased, impulse at times heaving and strong. Weak breathing all through both lungs. Urine healthy. Temper irritable. Left hospital Dec. 8th in same state. When he came under my care he complained of a constrictive sensation at the epigastrium, "like a rope round him.'' The same sensation was brought on by walking to some extent. At times he had a dreadful amount of flatulence. Appetite very good, but is afraid to eat. Looks well. Pulse 54, weak, intermitting every now and then. Heart's action trembling, the contractions appear to be not steadily sustained. Ordered argenti nitrafc. gr. | + extr. byoscy. gr. ij ter die, with ammonia, spt. seth. s. co., and tr. hyosey. On 21st and 22d he suffered much from pain in front of his chest during the night up to 4 A. M. On 24th he had pains in his chest as usual till 7 A. M. when he screamed out violently, turned over, and died immediately. I was informed that he had latterly had an attack twice or thrice daily, each attack lasting one hour, during this time the epigastrium was hard and swollen. In the intervals he was quite free from pain. Taking even very light food, or riding, or walking brought on the paroxysms. In one of the latter, if not the last, the pain extended to the left arm, affecting it severely. He used to open his dress and rub his chest when suffering. His wife thought he had a tendency to insanity. Post-mortem. — Lungs quite healthy. Some fluid in pericardium. Heart about normal size, very decidedly flabby, muscular tissue appeared healthy, large loose clots in auricles. Aortic valves did not hold water ; they were thickened, but quite flexible. Just above one of them, in the sinus of Valsalva, there was a large patch of calcareous deposit, about J by i inch ; it lay close to the orifice of a coronary artery. The coats around were healthy. Mitral valve a little thickened, but quite efiicieat. Right valves healthy. Muscular tissue of the heart was markedly affected with fatty degeneration, the fibres full of minute oil molecules, and their nuclei broken up into masses or streaks of oily molecules. Liver and stomach quite healthy. Body in good condition, muscles of a good dark colour, and in a decided state of rigor mortis, which was not the case with the heart. No. 99. — Mr. H., set. 57, a stout, large-made man, had been to the races on 27th, and rather deranged his digestion as he thought with melons and champagne. He complained on SOth of a very distressing pain across the ANGINA PECTORIS. 213 upper part of his cbest ''as if an iron network was there instead of flesh," but there was no disorder of the sounds or rhythm of the heart. He was very fidgety and nervous, and anxious for relief, and of his own accord applied hot water to his chest, so as to raise a small blister. The pain in his chest came on while he was walking up a hill on 27th and continued till his death. He had always a presentiment of sudden death, often spoke of it; his father died of disease of the heart. On 30th he had a dose of calomel + opium, some brandy, and olei ricini, and one dose of soda + acid, hydrocy. dil. Tt\^iij. Shortly after this he died suddenly, just after leaving the night- stool. Post-mortem — Lungs much congested, but crepitant throughout and healthy. Heart of normal size, cavities open, containing as well as the large vessels much fluid blood, and scarce a trace of clot. The heart's tissue was rather flabby, of good colour, the muscular fibres of both ven- tricles showed only fatty degeneration of their nuclei, the bulk of each fibre was quite healthy. The subpericardial fat encroached to some extent on the muscular tissue in some parts, but the walls of the cavities were not thinned. The left coronary artery was extensively affected by atheromato calcareous deposit, which narrowed at some parts of its canal decidedly. The right coronary appeared healthy, the mitral and aortic valves were healthy, the others were not specially examined. No coagula in the large pulmonary vessels. Tracheal and bronchial mucous membrane was very highly congested and dark. The abdominal viscera all appeared healthy. The stomach contained a little fluid ; its mucous surface was pale and normal. No. 100. — X. Y., a robust man, aet. 54, was under treatment a short time with inflammation of the left testis of moderate severity. It was getting better, and he was not otherwise ill at all He had been under treatment on previous occasions, but had never had any serious illness. About the middle of the day he was suddenly attacked with severe pain in the region of the heart. His medical attendant had seen him the same morning, and found him apparently well. In fifteen or twenty minutes the man was dead. Six leeches had been applied on three separate occasions to the testis ; the patient had sufi'ered some mental anxiety, but was in tolerably good circumstances. At the post mortem the rigor mortis was well marked, the body muscular, and in good condition. Heart flabby, its walls were perhaps rather thinner than normal, and its tissue of a less decided red. On microscopic examination some degree of fatty degeneration of the fibres was found, but not by any means enough to account for the fatal event. There was slight atheroma of the coronary arteries. Brain not examined. Thoracic and abdominal viscera healthy. Remarks. — The morbid changes in these three cases were mate- rially different, and yet the disease was in all I believe the same. In the first it is probable that the patch of calcareous deposit pressed on and irritated some nerve, which then exerted on the cardiac ganglia a depressing inhibitory influence. The degenerated mus- cular tissue would be all the more readily paralyzed from its enfeebled state. In the second case there seems no adequate explanation to be given of the sudden supervention of the symptoms, as it must be supposed that the disease of the coronary artery had existed for a long time, and the heart so to speak must have become 214 ANGINA PECTORIS. habituated to it. In the third case there appeared absolutely no cause for the fatal event. The occurrence of such cases as the last, the absence of any constant morbid condition in instances where organic disease is found, and the frequent existence of all kinds of organic lesions without any trace of angina incline me very much to believe that the essential circumstance in the disorder under con- sideration is an attack of neuralgia, quite similar to that which would be unimportant elsewhere. This seems to be nearly the opinion entertained by Trousseau, and is further supported by the complete cures of the disease which have occasionally been accom- plished. Bernard tells us,' and the observation is highly important, that irritation of a posterior spinal root causes temporary arrest of the heart's action continuing for fifteen or twenty seconds; he even intimates that in a weakened animal fatal syncope might be produced in this way. It is however noteworthy that cerebro-spinal neuralgia however violent does not (in the human subject) seem to have much tendency to induce syncope, whereas this is apt to ensue on irrita- tion of the sympathetic plexuses. If we conceive such a pain as a severe gastralgia befalling the cardiac plexus we may well imagine that it would occasion arrest of the heart's action. I am much inclined to coincide with Laennec's statement, quoted by Romberg,^ to the effect that " in a slight or moderate degree angina pectoris is an extremely common affection, and exists very often in individuals who are free from any organic affection of the heart or of the large vessels. I have seen many persons who have experienced only some smaut attacks, but of short duration, and who have afterwards been freed from them, I even believe that the influence of the medical constitution contributes to its development, for I have observed it frequently in the course of certain years, and I have hardly met with it in others." Romberg's statement that arthritis and hysteria are the chief predisposing causes of this disease appears to me by no means well founded, certainly at least as regards the latter. Neither can I remember to have met with angina in any of my gouty patients; I can scarcely think that the podagrous are notably more liable to the disorder than others. Rheumatism appears to me to have much more relation to angina pectoris than gout has, and this may be the reason that certain states of cardiac disorder of anginose character are remarkably relieved by pot. iod. I am speaking here of the apyretic form of rheumatism, such for example as produces a stiff neck. Believing as I do that angina pectoris is essentially a neuralgia, there is nothing surprising to me in the occurrence of minor degrees of it, or to speak more exactly, of various forms of dyssesthesia or neurosis of the heart. True, these are not likely often to pass into the graver disease, but they indicate nevertheless • "Legons," vol. i. p 269. 2 "Dis. of Nervous System," toI. i. p. 126. ANGINA PECTORIS. 215 the tendency of tlie nervous structures of the heart to be morbidly affected. This is a material point, as any tendency to implication of vital organs is always to be regarded with suspicion. Thus of two persons who on exposure to malaria should contract, the one a severe tic of the face, the other a moderate cardiac neurosis, I should have no question in estimating the former as the more lightly visited. It is perhaps impossible to offer any satisfactory arrangement of cardiac neuroses, the most useful way will be I think to cite some interesting examples I have met with, and to make some comments upon them. Before doing this I would remark shortly on the great influence of gastric disorder on the heart. This is a matter of the com- monest experience, but it seems to me to be by no means sufficiently explained. In the first place I think it must be allowed that mere flatulent distension of the stomach disturbs materially the action of the heart, the relief procured on dispersing the flatus being im- mediate. I should be much inclined to ascribe this disorder of the heart solely to inhibitory action of the gastric nerves, were it not that it is certainly aggravated by lying on the left side, which by bringing the weight of the liver and other viscera to press on the stomach pushes it upwards against the diaphragm and the heart. The cardiac uneasiness from this cause sometimes takes the form of a sharp precordial pang, which forces the person to turn immedi- ately from the left side position from the sensation that if he did not the heart's action would be arrested. The distress in this case seems to be of mechanical origin. There is certainly I think some peculiar relation between flatulency and cardiac disorder. A gentle- man whose heart is apparently free from organic disease, and who has no gouty tendency, but some rheumato-neuralgic, finds that when he has been debilitated by various causes, over-exertion in walking produces a tendency to syncope and flatulence. It appears as if both resulted from the same cause. He has no dyspepsia, but has found that sudden mental excitement or emotion will suddenly bring on flatulency when he was previously quite free from it. The extraordinary rapid development of flatus (rectal), which occurs not uncommonly in malarious dysentery, ceasing as suddenly as it com- menced, and taking the place of diarrhoeal discharge is almost sufficient to prove that flatulent disorder may be dependent upon nerve affection. No one can I think have had to deal with these cases without being impressed both with the neurotic character of the disorder and the utter insufficiency of any mere decomposition of intestinal contents theory to account for the phenomena. From my own observation of both gastric and rectal flatulence I am much disposed to lay down as a proposition, that mucous membranes under the influence of enfeebled innervation may secrete large quantities of gas. Trousseau' affirms that flatulent distension often occurs 1 " Cliniq. Med.," vol. ii. p. 354. 216 ANGINA PECTORIS. quite independent of fermentation. Cardiac distress and debility may be co-results of the same nerve disorder. The best remedies for cardiac uneasiness depending on flatulence are creasote in pills with quinine and a little ginger, or creasote in solution with muriatic acid and tr. calumbse. The following case is a well-marked example of the association of cardiac and gastric disorder. No. 101. — M. L., f., set. .53, ad. January 23d, ill three months. Com- plains of dreadful palpitation of the heart mostly felt at night, preventing her from lying down or getting sleep for hours; sometimes she can hardly breathe. The palpitation causes a hammering noise in head. Has much flatulence and spasm at the stomach (severe pain darting from between the scapulae to the sternum, and up into the neck). If she can disperse flatus is easier. Food does not digest, turns to wind. The heart does not appear enlarged, there is a loud rough systolic bruit at the base extending some way along the the aorta, second sound distinct lower down, rhythm normal. She says the heart seems to stand still at times. Is very weak, always thirsty. Epigastrium very tender. Takes no tea. Has prolapsus ani. Nitrate of silver with henbane was given with good eff'ect in calming the excited action of the heart, but muriatic acid with prussic and inf calumbae was rather prejudicial, a combination of strychnia, ferri sulph. and tr. zingib. proved however most useful. As long as she took it she had- toler- able appetite, and was able to digest and to lie down and sleep at night. The heart's action became much quieter, and the pulse notably weaker than it had been at first. Stout she found beneficial, but had to omit it occa- sionally. Mutton, cocoa, and bread she was able to digest very tolerably. In this case it is quite certain that the gastric disorder as well as the cardiac was a neurosis. Had it been otherwise the strychnia and iron would surely have proved the reverse of beneficial. Flatulent distension of the stomach no doubt aggravated the cardiac disorder, but did not originate it. Both were I believe co-results of the same neurotic condition, and both were benefited by the same treatment. The calming of the excited heart's action under nervine tonics is a curious and interesting phenomenon, and almost necessarily suggests to us the opposite results of dividing and galvanizing the pneumo- gastric nerves. In one very marked instance which occurred to me many years ago the patient had had diarrhoea, vomiting, loss of appetite, and sleepless nights for two or three days ; she was very weak, inclined to faint, and felt as if she would sink through the bed on which she lay ; yet the pulse was regular, large, rather forcible, 100. Under quinine 9 grains a day, she gained much strength, and the pulse became weaker, from the heart acting more quietly. The effect of large doses of quinine in slowing the pulse is very similar to that of galvanizing the pneumogastrics, and the result is probably attained through the same channel. It is in in- stances of the kind above related, well known to practical men, that we have good examples of the truth of the distinction made by Barthez' between radical and acting forces. The former may be 1 "Traite de Tlierapeut," par Trousseau etPidoux, vol. i. p. 43. CARDIAC NEUROSES. . 217 nearly exhausted while the latter are in full play; and vice versd the latter may be but slightly manifested while the former are powerful. The amount of the radical forces represents a person's capacity of vital resistance to disease and to fatigue. Two persons may have the same apparent strength and capacity for action, but one, to use an expressive term, has much 'more "last" in him than the other, withstands fatigue much longer, and resists hardship and morbific causes much better. The acting forces according to Bar- thez have their origin in the radical, and these are especially in- creased and sustained by quinine and other tonics, though of course they are dependent essentially on the due maintenance of the various vital processes by food, pure air, repose, &c. It is very noteworthy that there is often a distinct consciousness in the system that these radical forces are failing. The pulse and respiration may be good, there may be no evident signs of impending collapse, and yet the patient may feel that he is gravely stricken, and have a presentiment of dissolution which is not unfrequently verified. I well remember myself during the cholera epidemic of 1854, a full hour before I was attacked with a form of the disease, laying down the pen as I was writing at night surprised at the sudden strong presentiment of death which came over me. My mind was quite calm and clear, my bodily functions were unaffected, and I looked upon the feeling for some time as a curious psychical phenomenon. This however by way of digression. The depressing influence of certain matters taken into the stomach upon the heart is well known, as for instance that of large draughts of cold water, or of lumps of undigested food. Mr. Higginbottom has recorded' some well-marked examples of "syncope senilis" resulting from the latter cause, and relieved speedily by the administration of an ipecacuan emetic. Such cases seem to me best explained on the view of inhibitory action, the morbid stimulus being reflected from the nervous centres on the cardiac nerves. Tea is so notorious a disturber of the heart's tran- quillity that it needs little more than a bare mention. I am satisfied that it is not solely an idiosyncrasy which renders it a very poison to some individuals, but that acquired nervous debility may have the same effect. The gentleman whose case I have alluded to above used to take tea freely and enjoy it until the last five or six years without experiencing any ill effects. Now it renders him sleepless, hyper^sthetic, weak, and produces a sensation of precordial uneasi- ness and of failing action of the heart. Coffee if continued a few days has the same effect, but cocoa has not. The remedy in such instances is not only omission of the injurious article of diet, but the employment of all means capable of increasing nervous energy. It may be mentioned as illustrative of the change wrought in the nervous system by the toils and cares of life, that the same man to whom tea is now a poison drank it instinctively as the most reviving > "Lancet," April 20, 1856. 218 CARDIAC NEUROSES. beverage twenty-four years ago towards the close of an eighty miles' rowing match. Many Alpine tourists find cold tea an excellent refresher in their mountain clamberings. It is plain enough that to a tolerably firm nervous system tea is a grateful and useful stimulant. Its poisonous and depressing action on the weak and shaky system may be explained I conceive on the principle before referred to, viz., the production of hyperaesthesia by debility. When the nervous power has become enfeebled the plexuses of the coronary arteries partake of the morbid sensibility, and are excited by tea to produce contraction of the vessels. The heart is thus imperfectly supplied with blood, and its action is consequently feeble and flagging. In other instances where palpitation is produced it is probable that the stimulus tells more upon the muscular tissue of the heart than upon the coats of its vessels. M. Beau^ has lately remarked on the production of angina pectoris by the use of tobacco, and records eight cases in evidence, two of which proved fatal. Judging from the action of nicotine in tetanus, and from the effect of tobacco enemata it would seem probable that tobacco exerts a directly paralyzing influence on the heart. Rouget^ however shows by experiment that its action is the reverse, that when applied directly to the heart it causes a permanent tonic contraction ; and that if it be applied to the motionless and dilated ventricles of birds and mammals killed by the inhalation of chloroform, it restores for a time the contractions, and at last induces tetanus of the tissue. This statement goes to support the theory of spasm. The cases I propose to relate may be distinguished as rheumatic, malarious, saturnine, and connected with " goitre exophthalmique." No. 102. — C. R., a3t. 35, (?) of sanguine habit, but rather weak nerve power, had been exposed to cold more than once, and suffered from stiff neck and a most unaccountable malaise. His digestion was usually good. Four days later, having had a fresh chill in the interval, he took a hurried meal, and on returning had a nap as usual. He awoke with a very curious sen- sation of spasmodic choking all along the oesophagus. He went to bed and felt somewhat relieved by the warmth, so that he slept for about one hour. He then awoke in the most excruciating pain, could only lie in one position, viz., on the back slightly inclined to the right side with the left leg drawn up. He could not breathe without great pain. " I dared not," he says, " close my eyes from experiencing that most awful sensation as if my heart would cease pulsating, the agony I went through that night baffles all de- scription." For two hours he was involuntarily kicking; though well aware that he was doing so he seemed to have no control over his limbs; and if he chanced to kick himself the feeling was a most curious one, " as if one leg did not belong to the same body." A mustard and turpentine poultice to the chest afforded some relief. When I saw him early the next morning the pulse was excited, the tongue pretty clean, urine scanty and high-co- loured, sounds of heart and lungs healthy. He took calomel and opium of each gr. ij immediately, and had his chest rubbed with a liniment of aco- ' ".J. de M^cl. et de Chirurg. Pratiq.," July, 1862. 2 " J. de la Physiol.," 1860, p. 569. CARDIAC NEUROSES. 219 nite and opium. After sleeping two or three hours he awoke and began to take muriate of ammonia and bicarbonate of potash quater die. The next day the urine deposited a h»teritious sediment; he was much better, and in forty-eight hours from the time I saw him he was convalescent, and had no relapse. Both before and after this attack he has sufferred from rheuma- tism^ muscular and periosteal. In this instance it is quite certain that the disorder was a rheu- matic neurosis, and that there was nothing whatever imaginary in it. The nervous and muscular apparatuses of the heart and oeso- phagus were especially involved, as well as the intercostal nerves. According to Bezold' the nervous centre of the cardiac movements furnishing three-fourths of the entire propulsive force of the heart occupies the cervical region of the cord including the medulla ob- longata, and extends as low as the fourth dorsal vertebrsf. Its fibres run through the cervical spinal cord, and pass out between the seventh cervical, and fifth dorsal vertebra, probably passing through the lower cervical and upper dorsal sympathetic ganglia, and proceeding to the heart. If we suppose that in ordinary cir- cumstances the rheumatic disorder in the above case would have assumed the 'form of intercostal neuralgia it is not difficult to under- stand how by extending backwards and involving the origins of the upper dorsal nerves it induced the very peculiar cardiac distress. The involuntary kicking seems to have depended on an excited state of the lower dorsal and lumbar cord, the action being of a somewhat reflex character. The altered sensation was probably also due to central disorder. The case seems to me of interest from the evi- dence it aff"ords that neurotic as well as febrile rheumatism has a tendency to affect the heart. No. 103.— M. A. W., f., set. 44, ad. March 12th.

The attacks last half an hour and occur at irregular times now. ■ After this she took F. + Q. citr + pot. iod. gr. ij ter die, with which she " benefited very much, and by July 2d was fairly recovered. I regard the disorder above described as of rheumatic nature from the previous attack of rheumatic fever, which probably inflicted some damage on the nervous apparatus of the heart, from the good effect of pot. iod. and alkalies, and from the occasional lateritious state of the urine. I believe, though I cannot put my hand upon the notes of the case, that she had a son who died soon after of rheumatic heart disease. In her case the affection was evidently a neurosis, and though quite controlled for the time I think it is highly probable that it will return, and may be aggravated by gastric disorder or the like so as even to end fatally. The next group are instances of malarious infection. No. 104. — M. S., set. 41, of active but nervous temperament, latterly residing in London, but having lived for many years in Australia, was subject to winter bronchitis. Jan. 9th. Having had on the previous day marked symptoms of commencing catarrh she was attacked about 8 A M. with distress referred to the heart, a sensation as if she were dying, breath- lessness and anxiety. I saw her about 10 A.M., when I found the P. at the wrist almost utterly gone, the hands cold, the same distress continuing. The action of the heart on auscultation was very rapid, the sounds normal and loud, the face pale, and the eyes sunken. Her voluntary muscular power was not materially impaired; she sat up readily, and stretched her limbs vigorously. More than once she expressed a dread of going to sleep lest she should never wake again. She seemed too restless and anxious to sleep or lie down. Stimulants were given freely, mustard poultices applied to the precordia, and the interrupted current passed from the nape of the neck to the same part. Very little improvement was produced for some time J the P. continued fluttering and most indistinct, but at last warmth began to return in the hands, and the P. improved. She took gr. iij of quinine at 11 A.M. and 1.30 P.M. For a good while before and after the latter hour the cerebral functions were much disordered. There was evi- dent delirium. About 4 P. M. she became much quieter, but complained of extreme weakness. The P. was 108, of tolerable force; the T. remained clear, but appeared to her to be dry, though it was fairly moist. She vom- ited once about the middle of the day, and coughed up a few times a little phlegm; butalmostallthe catarrhal symptoms had disappeared; 10P.M. com- plains of extreme debility and perspiration breaking out. Quinine gr. iij at 5 and 9 P.M. In the course of the next day gr. iij of quinine were taken, and at the same rate for another half day. She then had a little calomel and rhubarb, after which she slept well. No medicine was now given till 15th, when she began citrate of quin. and iron, gr. v ter die, which she took for nearly fourteen days, and was quite well by 30th. The cardiac symptoms never recurred severely, but she had more than once uneasy sensations about the chest, which made her fear a relapse, such as fluttering action of the heart and great weakness. One of her daughters about the same time had an attack of bronchitis attended with a decided aguish disorder recurring every morning, consisting of shivering and depression, and ceasing under the administration of quinine together with the bronchitis. CARDIAC NEUROSES. 221 Feb. 3d. M. S. was attacked again about IIP. M. with decided rigors, and violent beating of the heart in repeated paroxysms, with great depression and mental disturbance manifested as before by constant loquacity, and a tendency to repeat the same question over and over again. The P. at 2.30 A. M. when I saw her (4:th) was soft and quick ; the skin fully warm ; the T. parched and dried up and coated. She complained of breathlessness, threw the clothes ofF her, her legs felt as if they did not belong to her, and her hands tingled. I gave her liq opii sed. + spt. geth. chlor. and the symp- toms gradually subsided. At 7.30 A. M. she began to take quin. dis gr. ij 3 tiis horis. 5th. Was better all yesterday until IIP. M. when the same symptoms recurred, but less severely. She got some tolerable sleep, but experienced in the morning some disorder of the heart's action with a feeling as if she were dying. This subsided after some time, and she re- mained till the afternoon weak and depressed. She was cinchonized. 7th. After a tolerable day on 6th, the appetite however being very bad, she began to have about 9 P. M. " internal tremors," and exceeding restlessness, which passed into high fever and was succeeded by profuse sweating when she at last got to sleep. This morning is very weak and prostrate with utter aversion to food and much nausea. Ice to swallow and mustard poul- tices to epigastrium. On 8th resumed quin. dis. gr. ij ter die, and on the 10th began ferri and quin. citr., this she took with benefit for four days, and then went to the country. She returned in about a month much im- proved, but having still in the evenings slight byt distinct paroxysms of aguish character. Nov. 7th. Up to about this date she continued well and active; she woke up about 2.30 A. M. with palpitation and distressing uneasiness at the heart and pain in the back. I saw her at 4 30 A. M. and found the heart beating rapidly, its sounds very clear and sharp, the P. thready and indistinct, and the hands coldish. She was wakeful and afraid to sleep ; her legs felt as if they did not belong to her. After two doses of chloric ether + liq. opii sedat. the P. became more distinct, the pain in the back less, the hands warm, and she went oflF to sleep. With quinine and iron she was well in about ten days. It is now nearly six years ago since these attacks occurred, and there have been no signs since of any serious heart affection. I have the most perfect assurance that in the above case there was an entire absence of all hysterical fancy. The patient had passed much of her life amid the stirring scenes of a colony, and was one of the last persons in the world to plague herself and others "with imaginary disorders. She had once been accidentally poisoned with sulphate of zinc, and had never had the same health since. She had also once suffered with a head affection from excessive heat, ■which subsided after an eczematous eruption had appeared on the scalp. The first attack, which was the severest, had a very serious aspect; her own apprehensions of impending death were very strong. I was puzzled by it at first, as I could not see why the pulse should be absent while the heart was acting violently. In the subsequent attacks when I had a clearer notion of the causation of the phe- nomena the course to be pursued was apparent. The attack was in fact essentially the cold stage of an ague, in which, owing to a peculiar irritability of the vaso- motor nerves, the arteries were 222 CARDIAC NEUROSES. unusually constricted. The circulation was thus seriously interfered with, and the heart had to struggle against the obstruction. As soon as the arterial spasm yielded the difficulty and danger were over. The cerebral disorder shows how specially the nervous system was affected by the poison. In the subsequent attacks there seems to have been less spasm of the remote arteries than in the first, and perhaps the cardiac plexus was more directly affected. The feeling of impending dissolution assimilates the state a good deal to angina. It is worth remarking that in this instance, as well as in No. 102, there occurred the peculiar symptom of not daring to sleep, and of the lower limbs feeling as if they did not belong to the body. The apparent relation of the disorder to influenza, its distinctly aguish character, and the occurrence of aguish bronchitis at the same time in another member of the family are points of much significance. The remarkable case related by Dr. Stokes' seems to me to have resembled the one just recorded. In the former, a rather mild case of maculated typhus, the heart's impulse was strong and the sounds remarkably distinct on the 8th day, and continued so until the 15th, though no pulse could be perceived at the wrist. The surface was icy cold, and of a violet hue, the countenance sunken, and the skin and breath cold. Stimulants were of no avail. On dissection no organic lesion of any kind could be discovered in any part of the body ; the heart was firm and its muscular structure natural ; no obstruction existed in any artery, but the whole quantity of blood seemed much diminished; its consistence was somewhat pitchy and its colour very dark. The wound made in the arm (for injecting blood) was still gaping, and presented not the slightest appearance of adhesion or inflammation. Knowing as we do how weak a con- traction is sufficient to send a pulse-wave through open arteries I cannot conceive that in this case the vessels were free from obstruc- tion, and as no embolon, &c. was found at the autopsy it seems pretty certain that they were occluded by spasm of their circular coats, which naturally disappeared after death. This view is strongly supported by the icy coldness of the surface, and of the breath, phenomena which are rarely if ever observed except under such conditions of the nervous system as exist during the algide stage of fever. Had the failure of pulse been owing to cardiac debility, the organ would not have been found firm after death, nor would stimu- lants have been so ineffectual. The warm bath would probably have been the best remedy, as it proved in a case to be presently men- tioned. The observation is one of great importance as showing that algide symptoms, the result of vaso-motor nerve irritation, may occur in typhus fever. On talking this case over with Sir R. Martin he made the sagacious remark that the patient must have had malarious disease previously. Nothing is said about it, but it is highly probable. * "Dublin Q. J. of Med.

Z., m., fet. 37, had previously suffered from ague and from recurring neuralgia, and had just returned from a malarious district. About the middle of the day he was attacked suddenly with faintness, and after taking some ether vomited. The syncope increased and became alarming, requiring the frequent administration of restoratives and friction to the surface. In the evening he had a dose of calomel and a rhubarb draught. The night was sleepless, and the next day he was very prostrate, remained in bed, unable to eat or to exert himself In the evening another attack of syncope came on from which he was rallied as before. Ten grains of quinine were now given, and early the next morning, ten more. He was feverish in the night, but with an opiate had some sleep. The next day he was better, had no faintness. From this time he gradually recovered, but was unfit to work for some time. Several years have elapsed since the above illness, but there has been I believe no recurrence, nor any indication of disease of the heart. Recamier cites two very instructive instances of the same cha- racter as the foregoing. In the first, a man, set. 35, of good con- stitution, felt some lipothjmic symptoms which soon ceased, and recurred the next day at the same hour. No preventive means were used, and in the third attack the man died. No adequate cause for the fatal event could be found at the post-mortem. In the second a young lady, get. 19, was affected in the same way, but after the second attack bark was administered rapidly in full doses, and she was speedily cured. Torti relates (Therapeut. Spec, p. 435) a case of syncopal tertian which appeared almost utterly des- perate, but yet after the last rites of the Romish Church had been administered the patient was snatched as from the jaws of the grave by the use of bark. Hamilton mentions^ a case of " terciana syn- copal" occurring in Peru. The subject was a negro, set. 40, with a finely developed head who managed an estate for his master. He ■was as usual in the field in the morning when he fell on the ground and was conveyed on a mule to his master's house in town. When first seen after his arrival, he was more like a corpse than a living man ; the pulse at the wrist was scarcely to be felt ; skin cold and dry ; little or no shivering ; speech lost ; but his vision and hearing appeared intact. The first thing done was to put the patient into a warm bath, which seemed to operate as a charm, for the breathing became freer, the pulse rose, and speech returned. After leaving the bath the hot and sweating stages of the disorder appeared. It •was ascertained that the bowels had been confined several days. He was freely purged with calomel and rhubarb, took quinine and was well in ten days. It is stated that such cases there are generally fatal, and that those who are taken ill are given up for lost. Trous- seau {CUnique Medicale, vol. ii. p. 763) mentions two cases in which death seemed actually to have taken place, but which were nevertheless restored by bark. Cardiac paralysis was no doubt the 1 Hamilton's "Practical Obs. on the Intermittent Fever of Peru." Highlev, 1842, p. 27. 224 CARDIAC NEUROSES. cause of death in some of the cases at Walcheran, of whom Sir G. Blane says, " Under the influence of the endemial air recoveries were slow and imperfect, and relapses very frequent, so that some of the convalescents when apparently doing well would unaccountably drop down dead. Slighter degrees of the same affection are I believe by no means uncommon as sequelae of malarious fevers. In a case of remittent fever under my own care the patient was at- tacked one night by an alarming sensiition referred to the heart attended with faintness and a failing pulse. He thought himself dying, and said it seemed as if life was ebbing from him. After he had become convalescent this cardiac disorder continued to recur about every second day, and was especially induced by any painful emotion or agitation. As the testimony of an independent observer is of great value, I subjoin an abbreviated account of an attack in which this same patient came under the observation of Dr. Symonds, of Clifton. He was called one afternoon to see him in haste, and found him, he says, in a rather puzzling condition. " There were indications of some very distressing sensations about the precordia; he pressed my hand against his side as if suffering some spasmodic pain." He had complained the day before of pain in the heart. " He was, however, so very delirious that one could not be quite sure that the local feeling was not some delirious dysaesthesia. His pulse was weak, small, not quick, hands and feet cool, head hot, eyes suf- fused. He talked delirious of matters in which he had been engaged some months before." Dr. Symonds doubted whether some decisive remedies should not be applied to the head, but, guided by the state of the circulation and the character of the neurotic symptoms, he ordered for him brandy, a full dose of calomel + opium, Hoffmann's ether and ammonia. Five hours later he was much better, quite conscious, had passed an enormous quantity of pale limpid urine, but still had pain in the region of the heart. " The case was now clear — feeble heart, pseudo-angina pectoris, and a neurotic diathesis heightened and disordered by the malarious influences to which he had been subjected. With quinine, valerianate of zinc, creasote, and opium, and occasional alterative doses of calomel, he was soon convalescent." I was consulted in the case of a young officer, a model of physical conformation, and apparently in good health, who had been the cock of Eton, but after his return from India suff'ered with such a distressing dyssesthesia referred to the heart that he could not walk a mile without feeling that death was imminent. There was nothing apparently wrong about the action of the heart, nothing to be detected on the most careful examination. Yet I do not think he was malingering, both from his serious alarm about his malady, and from his not applying for any certificate to prolong his leave of absence. Sir R. Martin informs me that cardiac debility, as marked by an intermitting pulse is an extremely common result of residence in India, and my own observation of returned Indians has generally shown a markedly weak state of the circulation. CARDIAC NEUROSES. 225 Whether this dehility aifect the nervous apparatus of the heart solely, or its muscular tissue, or, as is most probable, both, I do not undertake to decide. There can, however, be, no question that the nervous system is principally implicated; no one can have had much to do with malarious disorder without observing how large a part the nervous system plays in the multiform phenomena that present themselves. The treatment of these cases is in one respect plain enough, viz., that they require invigorating tonic remedies, among which we must always rate highly pure air and generous diet. But in another respect, and that one which may be of momentous impor- tance in perilous cases, our course is not so clear. Supposing in an attack of cardiac angina of presumed malarious origin we find the heart's action very depressed and we dread death from its failure. This condition may arise on the one hand from irritation of the sympathetic plexuses causing constriction of the coronary arteries and so depriving the heart of an adequate supply of blood ; or it may depend on a paralysis of the cardiac nervous centres and nerves. In the first case sedatives would be needful, in the second stimulants. The diagnosis must, I think, chiefly rest upon our being able to ascertain whether or not the affection can be regarded as coinciding with the algide stage of an intermittent, as marked by the usual signs. If so, it is probable that the coronary arteries are in a state of constriction, and we may either give opium with chloric ether, and a warm bath ; or, if the distress is less urgent, wait till the spasm spontaneously subsides. In the other case a large dose of digitalis would probably be advisable together with free stimula- tion. In doubtful instances it will be safest to give stimulants and to apply an effectual mustard poultice to the precordia. This may by its powerful excitation of the cutaneous nerves both arouse the cardiac centres, and remove the irritation of the sympathetic plex- uses. It sounds rather contradictory to talk of removing a state of irritation in one set of nerves by setting up irritation in another. Yet as a matter of experience it seems true that such may be the case. The common practice with the laity of applying a mustard poultice for the relief of all sorts of pain, including neuralgia, is not so bad as at first sight it would appear. Duchenne, quoted by Trousseau {Tr. de Therap.^ vol. i. p. 787), says, "It is a capital fact that a sharp and sudden pain excited at any point of the cutaneous surface possesses the property of modifying profoundly certain sciatic neuralgias." The matter may be put in this way. When we feel a pain, or have an irritation in any part, all that we can say is that the nerve or nervous centre belonging to that part is in a morbid state, which is generally functional and removable. Now if we transmit through some other nerve a strong excitement of a different kind to that centre we may succeed in abolishing the ori- ginal morbid action, supposing it to depend on no actual organic change. We all know how any matter that interests us much makes us unconscious for the time of any minor disorder, and cases are on 15 226 CARDIAC NEUROSES. record where a strong mental emotion has dissipated actual articu- lar gout. The virtue of emetics in certain inflammations depends on their action on the nervous centre of the inflamed part. In giving opium in any case of cardiac affection we should be guided very much by the degree of pain. Should this be severe, we may give a moderate or full dose, ^ xxv — 1, but if the syncopal tendency predominate, we should be very cautious in giving opium lest we increase the depression. The good effect of the warm bath in Hamilton's case was very striking. It acted no doubt as a relax- ant, opening up the arteries and allowing the circulation to run freely. Of course it should not be so prolonged nor the temperature so elevated as to cause faintness. In the case of X. Z., No. 105, on the contrary, I am much in doubt as to the exact state of the heart, the general tenor of the phenomena was much more that of direct depression and semi-paralysis of the organ than of arterial constriction and ansemia. I have been the more inclined to notice the point I have just referred to, as it has occurred to me in some painful instances to observe the utter inefficiency of stimulants when sinking had set in. Brandy poured down as long as the patient could swallow had no effect. Of course I do not doubt the value of stimulants in states of depression, but I cannot avoid posing the question whether failure of cardiac action may not arise in different ways, in one from direct paralysis of the cardiac nervous centres and nerves, in another from irritation of the vagi or of the medulla oblongata, and in a third from general arterial constriction combined or not with a similar state of the coronary vessels. The following instance of cardiac disorder was confidently referred by the patient to the use of lead under his anvil, and he has had no relapse since the lead was removed. I do not, however, feel abso- lutely convinced that the case was one of saturnine intoxication, as the gums presented no blue line, but I think this is the most prob- able view. Lead was found I believe in a quantity of powder removed from under the anvil. No. 106. — J. R., get. 28, a hearty man, ad. Dec. 27th, ill fourteen days.

Mr. Pye Chavasse records^ a remarkable case of great nervous prostration with right side anaesthesia, anxiety, and palpitation of the heart (which was sound) on the slightest exertion, which seems certainly to have been occasioned by the use of water impregnated with lead. " The blue line on the gums if not altogether absent was at all events very faint." In my own case, as in Mr. Chavasse's, it is a strong point in favour of the lead poisoning view that the patient recovered so completely after removal of the presumed cause. Had it been otherwise, had he suffered from foul air, general de- bility, influenzal miasm or any other depressing cause, he would have been much longer in recovering, and would in all probability have relapsed. He is now strong and hearty. In such cases the cardiac nervous centres seem to be directly affected, to be semi-paralyzed. No. 107.— A. R., f , set. 26, ad. Jan. 22, 1858.

Thymus gland very large, weighed 1,200 grains; it overlapped the pericardium, lay upon the aorta and pulmonary artery, and reached down to root of left lung. Thy- roid gland much enlarged. Brain healthy. The symptoms in this case indicate the existence of a primary neurosis of the vagi nerves of a paralytic kind. The phenomena bear considerable resemblance to those produced by division of these nerves. The excited quick action of the heart is a constant result of this operation, and after death the lungs are often found more or less engorged and condensed. The attack of pneumonia which so suddenly supervened and so rapidly proved fatal was probably the result of some casual catarrhal (influenzal) agency affecting a system highly predisposed to pulmonary congestion and consequent effusion. Budd^ and GulP have both noticed the occurrence of low or gan- grenous pneumonia from the compression of the pulmonary nerves by tumours of various kinds. The slight anatomical change found in the mitral valve is quite insufficient to explain the pain and pal- pitation which so frequently recurred. It seems impossible to regard them as other than functional disorders, especially as they varied so much. How far they were dependent on injurious pressure exercised on the vagi nerves by the enlarged glands must remain uncertain, though my belief is that no such pressure existed. I have certainly seen cases with very much greater glandular enlargement where no such symptoms were present. The thyroid enlargement and the proptosis are difficult to account for satisfactorily ; but the common occurrence of goitre as the result of malaria indicates its dependence on the vaso-motor nerve paralysis and consequent hyperaemia, and the same conditions were probably concerned in inducing the prop- tosis. Thus if we suppose hyperasmia of the tissues contained in the orbital cavity to issue in serous effusion, which is no very un- likely event, the globes would be protruded. I have at the present time two cases under my care which exemplify the influence of hyperaemia and serous effusion in causing this condition. In one where the proptosis has supervened quite recently, there is strong pulsation of the carotids, pain in and behind the globes, tension of the lids and great congestion of the conjunctiva. The patient is epileptic. In the other the proptosis is of old standing, there is no tension or redness of the lids, but there is a quasi-oedematous swell- ing all round the orbit, an evident pushing out of the integument. Pressure on the eyeball does not cause it to retire much into the orbit, but it certainly makes the bulging integument more tense. In this case there is serous effusion, in the former congestion. It is possible also in some cases that an enfeebled state of the recti muscles contributes to the proptosis. Eor further remarks on this 1 "Med Chir. Trans.," 1859, vol. xlii. p. 215. 2 u Guy's jjosp_ Reports," 1859, p. 307. CARDIAC NEUROSES. 229 subject I may refer to a highly interesting case published by me in the Med. T. and G-az., Jan. 2d and 9tb, 1864. In this though cardiac symptoms were not so prominent there was extreme debility, cough, and gastric disturbance, which brought life into very con- siderable peril. Under sedative and tonic means she was quite restored excepting the goitre. It is abundantly clear from the pre- ceding cases that an affection of nerves supplying vital organs may be a very serious thing, and that the prognosis should in such cases be guarded. A common form of cardiac neurosis is that where the action of the heart is much accelerated, ranging from 110 to 140 in the minute, in the standing position, and not falling much below the former figure in the sitting. The contractions are abnormally sharp and vivid, the organ seems to spring up with a quick forcible leap against the ribs. The apparent excess of action misleads the prac- titioner sometimes to suppose that there is hypertrophy. Percussion however shows that no enlargement exists, and auscultation detects no vascular bruits, nor derangement of the rhythm. The feeble stroke of the radial pulse often contrasts markedly with the vivid action of the heart. The general condition of the patient exhibits more or less evident indications of debility. Dyspepsia is often present to some extent, but is by no means always the essential cause. Tea on the other hand seems in some cases really to be the " fons et origo mali," the symptoms subsiding materially on its omission. I think the pathological condition in such cases is essen- tially hypersesthesia either of the nervous centres or of the sensory nerves of the heart, perhaps especially of those fibres distributed to, the endocardium of the ventricles. The hypersesthesia is as in other instances the result and associate of debility. The feebleness of the pulse shows how ineffectual the apparently forcible contrac- tions of the heart are. In fact the ventricles do but grasp the blood for a moment, and relax again immediately before they have fully emptied themselves. A case at present under my care illus- trates well how much more efficient a slower and more sustained action may be. An elderly man complains only of lassitude, has no dyspnoea, no indication of defective circulation. He is anaemic, but has no nerve disorder whatever. His pulse when first seen was only 20 ; there was scarce any impulse to be felt, the sounds were indistinct, and similar to each other. With iron and ol. morrh. the pulse has risen to 32, and he has become stronger. In this man it is evident that the heart contracts steadily and quietly on the blood in its cavities and expels it fully. There is no spasmodic jerk in the contraction, and consequently no notable impulse. Dr. Lyons^ has recorded a remarkable case which is as follows. A male, between 30 and 40 years of age, began to suffer at first with debility and unpleasant sensation in the chest ; after a time I "Dublin Q. J. of Med. Sc," May, 1862. 230 CARDIAC NEUROSES. could not leave his room, and scarcely could stir without increasing the heart's action. During the periods of excitement of the heart's action the debility was extreme, the patient's sufferings most intense, and the cardiac action almost more violent and tumultuous than Lyons had ever before witnessed. The face was flushed vividly, the pulse was 120, regular, and not remarkable for force or volume. The impulse was very violent, and a loud, diffuse, systolic bellows murmur was audible with great and equal intensity over the whole precordial region. Iron and tonics failed to give any relief, but vesication continued for ten months was of some service. After about five to seven years he completely recovered, and the most careful examination was unable to detect anything in the least de- gree morbid about the heart or any other part, Lyons considers this case to have been one of pure uncomplicated myocarditis. To me it appears more probable that it was an intense neurosis of the above kind, for these reasons : I cannot think that a myocarditis could exist for years without destroying life, or at the least seriously damaging the tissue of the heat, or of its valves by extending to them. Moreover an inflammation would so weaken the muscular fibres as to prevent the action of the organ from being excessive.^ On the other hand the extreme debility, the intense suffering, and especially the long continuance of the disorder are much in favour of its neurotic character. The treatment of cardiac hypersesthesia is too often unsatisfactory, probably because it is impossible to obtain rest for the organ. An irritable brain or stomach may be soothed by giving them timely repose, but we can do this but very partially with the heart. Avoid- ance of all emotion and excitement is very desirable, and the diet must be scrutinized to see whether some of its component articles may not produce or increase the hypersesthesia. In severe cases occasional small leechings may be recommended. Belladonna plas- ters are generally useful, and I should expect benefit from hypo- dermic injection of opium into the precordia. Internally I have seen most benefit from tr. digitalis, "Ixv ter die, but I am not al- together satisfied how far it is quite safe to give this drug in states of cardiac excitement. In conditions of cardiac languor I have no fear of it, but in the opposite I think we need to be cautious. In some cases aconite and hydrocyanic acid may be useful, but they have not served me well. Opium and nitrate of silver might be suitable remedies, especially where there was irritable dyspepsia. The very possible dependence of the disorder on some remote, per- haps little heeded, irritation should not be forgotten. ' Demme states that the most constant and manifest symptoms of myocarditis are decrease of the heart's energy, loss of rhythm in its movements, increasing frequency of the pulse, steady diminution of its size, and its continuous undulattry character. — V.

Remarks. — In both these cases the phenomena seem to be referable to a semi-paralysis of the pulmonary branches of the vagi, a sort of anaesthesia in consequence of which the reflex inspiratory actions could not be per- formed with their normal facility, but required the assistance of volition. Debilitating disorder was present in both instances, viz., menorrhagia in the female, and obscure nocturnal remittent in the boy. The good eff'ect of nerve tonics was very marked. As under these the general power was improved, the ansesthesia yielded. In contrast with these I may cite some instances of an opposite kind. No. 110.— E. C, f., aet. 52, ad. January 29th.

Remarks. — These cases are examples of a not uncommon pulmonary Deurosis, in which together with marked general debility, and more or less local vascular congestion there exists predominating hypersesthesia of the nerves of the air-passages. When the hyperaesthesia is considerable, and there is but little catarrhal affection, atropine has approved itself a very val- uable remedy. If there were much vascular congestion I should prefer opium. Where the debility is great strychnia and iron, aided usually by the sedatives, should be employed ; they seem by imparting tone to lessen the undue excitability of the nervous structure. The peculiar attacks of insensibility which occurred in No. Ill were not, I believe, at all dependent on congestion of the brain, but rather on a spasmodic contraction of its arteries, such as we suppose to occur in the " petit mal" of epilepsy. They ceased under the tonic treatment together with the cough.* I look upon ' In a patient under my care with pretty severe bronchitis attacks of insensibility- sometimes occur when he has coughed less than half a minute, so complete that he has fallen down and hurt his face, while at other times he coughs for a long while without losing consciousness. RESPIRATORY NEUROSES. 233 tbem as analogous to the cerebral disorder which a gastralgic patient re- cently under my care complained of. He stated that the pain made hira light-headed at times ; he felt as if his senses were going away. He was cured by strychnia, iron, and opium. In this case there could be no ques- tion of any cerebral congestion. ^ Pertussis is of course the capital example of a specific bronchial hypersesthesia. The excitement of the vagi nerves, however induced, is clearly peculiar and not identical with that just noticed. It is consequently much less under the control of remedies. I do how- ever by no means agree with Romberg that treatment is so ineffec- tual as he seems to consider it, and I believe that most physicians still retain faith in the utility of j'arious measures. Dr. Whitehead has adduced^ evidence showing now much the duration of the dis- ease can be diminished by treatment. Thirty-five cases not treated till the disease had lasted three months were cured on an average in less than twenty-five days; and eighty-seven whose treatment was commenced within fourteen days after the onset were cured in the same time. Opium, usually as Dover's powder, and belladonna were the principal remedies. Trousseau, referring to Bretonneau's treat- ment of the disease by belladonna, says,^ "Nous avons pu nous- memes constater I'extreme efficacitd de ce moyen," and Vollant^ affirms the same in the strongest terms. The latter uses only the powder of the root, which he gives in doses of gr. i, increasing the number from one to four or five a day till the paroxysms begin to subside, when it is given less frequently. Dr. West confirms to a great extent Dr. Hamilton Roe's testimony of the efficacy of prussic acid, and has only in one instance out of many hundred known any actually poisonous effects to be produced by it. _ The evidence for the real remedial power of this drug is worth considering, and our conclusion in its case may be applicable to others. Its sedative effect in some gastric hyperaesthesias cannot we suppose be questioned. It may therefore be admitted that it acts as a calmative to the filaments of the vagi distributed to the stomach, and consequently it is very probable that it will affect in the same way those which proceed to the lungs. An unbiassed and thoroughly reliable observer as Dr. West, tells us that in some cases it " exerts an almost magical influence on the cough," while in other cases it seems perfectly inert and sometimes injurious. Does not this warrant our regarding hydrocyanic acid as a remedy which may serve us well, but may also fail us, and forbid our rejecting it alto- gether ? Moreover there is some ground at least for believing that it is not a matter of indifference what preparation we use. Much of the variability in the results obtained from this as well as from > "Third Report of Clinical Hospital for Children at Manchester, 1859." 2 "Traite de Therap.," vol. ii. p 71, * "J. de Med. et de Chirurg. Pratiq.," vol. xxxiii. p. S61. 234 RESPIRATORY NEUROSES. other remedies depends no doubt on the dissimilarity of the prepara- tions employed in diiferent instances. We have just seen that Vollant lays stress on the use of belladonna root, deeming the leaves to have little efiScacy. Hepp insists on the importance of carefully following Withering's directions in collecting and preparing digitalis. Not more than a year's supply he says should ever be kept. Is it not pretty nearly certain that nearly worthless drugs are too often employed ? Bearing in mind the above, I am not at all shaken in my belief of the utility of treatment by finding that a great variety of remedies have been found or considered capable of arresting or diminishing the disorder in some instances while they have entirely failed in others. This, even admitting the purity and equal virtue of the preparations, as I have already observed, is a feature, common to many disorders and especially to neuroses. The idiosyncrasy of the individual patient, and the existence of numberless shades of difference in the nature and quality of the morbid processes are quite sufficient to prevent our remedies from having that certainty of action which many look for, and not finding become sceptical of all therapeutic agency. Even with regard to non-specific bronchial hypersesthesia after considerable experience I have no certain fore- knowledge as to whether atropia, opium, or cannabis indica will be successful in a given case. I am quite ready to charge some of this uncertainty to my own want of discernment, but I am certain that cases are not uncommon where the symptoms are to all appearance quite the same and yet the same remedies will have very different effects. One of the chief mistakes current at the present day is to regard all diseased states to which the same name can be applied as exactly and essentially similar, whereas the truth is that the same name covers a multitude of morbid conditions which vary ad infini- tum in their component elements. The gross, outward resemblance leads us to overlook and neglect the concealed but more important differences. This is the more to be regretted as the latter rule the treatment. With regard to pertussis I am much inclined to regard hydro- cyanic acid as suited to an earlier period of the disease than atro- pine is ; I give it during the catarrhal stage with vin. ipecac, and a saline. Combined with nitric acid it is very suitable also to a later period when the catarrhal affection is less acute, the dry have given place to moist r^les, and the febrile movement has subsided. When the cough is very violent and the catarrhal affection is slight I 'ex- pect great benefit from atropine. I have however seen it in combi- nation with nitric acid act exceedingly well in an infant suffering with severe bronchial catarrh complicated probably with miliary tubercle. As to the objections raised by some against employing such potent agents especially in young subjects I think it may be fairly replied that medicine cannot be practised at all without care and attention, and a very moderate amount of these is quite suffi- cient to prevent the possibility of any injurious consequences from PERTUSSIS. 235 the administration of any of the alkaloids. It may be affirmed that atropia is actually safer to use than opium. The latter, if an over- dose is accidentally taken, is more likely to be lethal than atropia, unless indeed the dose is very large. In the convulsions occurring in severe hooping-cough I have found atropia of some benefit, but not of so much as I had expected. I am doubtful at present whether opium is not preferable. The following case is a good example of a combined treatment which will be suitable in many instances- No. 114. — A. S., f., set. 7, ad.

Bromide of potassium has lately been given by several physicians with very good results. From two to five grains is the dose for a child from two to five years old. Bromide of ammonium may be used in the same way. The affection termed laryngismus stridulus, or spasm of the glottis, is one of peculiar interest, not only as a well-marked instance of nerve disorder capable of receiving a satisfactory explanation from established principles, but also on account of the great peril to life attending it. The child which but a minute before appeared toler- ably well may the next be laid lifeless in its parent's arms. The suddenness of the stroke which we know may fall at any moment adds much to the painful interest with which we must regard these little patients. The two following cases will serve as a text for some comments. No. 115. — A. R., m., set. 2, ad. April 6th, ill two months.

The relation of the disorder to dentition in this case was not at all well marked, nor was there any other apparent exciting cause. I believe the nervous centres were more at fault than the peripheral structures. The tonic probably arrested the disorder by lessening the excitability of the medulla oblongata. The weakly condition of the little patient was presumably the cause of the morbid state of this centre. The nervous erethysm was neurolytic. No. 116. — Gr. H., m., set. 10 months, seen Jan. 17th, 1861. Is suffering severely with attacks of spasm of the glottis which occur about every twenty minutes. The affection commenced gradually with very slight attacks six weeks ago; it has been much worse during the severe frost. About sixteen days ago he had a well-marked convulsive seizure which has not recurred since. In the attacks he first turns pale, throws his head back, the commis- sures of the lips are drawn backwards in a kind of grin, the face becomes sub-livid, there is a period of silence, and then comes the peculiar stridulous inspiration, which recurs several times, and is followed by a natural cry. He is greatly depressed, his face looks sunken, he seems ill and rather emaciated. B. rather costive. No fever.

This afternoon he had a sharp attack of convulsions, and during the whole evening and early part of the night had frequently glottic spasms, and was crying with pain.

Numerous and severe attacks of laryngismus lately, and this morning a fit of convulsions, in which his face was markedly pale.

At the beginning of LARYNGISMUS STRIDULUS. 237 June he went into the country where he remained about three months, and returned quite restored. He is now cutting his first molars, and though he has had some catarrh there has not been the least return of the laryngismus. Jan. 1864. No return of the disorder, the child has thriven well. The relation of the disease in this case to dentition is by no means clearly established. It certainly supervened about the com- mencement of the process, but it subsided long before it was over, and the aggravations of the disease did not evidently correspond to the period of eruption of a tooth. Whether there was some deep- seated irritation connected with the development of the teeth can only be conjectured ; if so, it only existed during the formation of the earlier teeth. The three points which the history seems to set forth prominently are, (1) the connection between the disease and general convulsions ; (2) the good effect of morphia and the inutility of belladonna ; (3) the importance of change of air. The occur- rence of general convulsions in connection with laryngismus indi- cated that the morbid action extends to and involves some larger group of nerve cells than in the local spasm, probably either the whole of the medulla oblongata, or the corpora quadrigemina also. The convulsions as well as the glottic spasms appeared to depend much more on a state of erethysm of the nervous centres than on any peripheral irritation. I mean that the former was much the more important causative element, the removal of which would have arrested the morbid phenomena. This is evidenced also by the " juvantia," sedatives affording relief, while lancing the gums had no decided good effect. I am much inclined to refer the superven- tion of the disorder to the severe cold of the winter which depressed and deranged the " vis nervosa." The first attack of general con- vulsions occurred during a hard frost. In this instance as in some others it has certainly appeared to me that the prevalence of severe cold has materially promoted the occurrence of general convulsions. The cold seems to depress the nervous power of the little patients, and make exciting causes of disorder more operative. The inference from this is that the child should be kept during cold weather in a well- warmed room, at a uniform temperature say of 64 deg. F., and that this should be maintained night and day. The sudden death which is by no means uncommon in this disease depends I conceive on the transmission of irritation along the cardiac fibres of the vagi to the heart, which is then arrested in its action just as when the pneumogastrics are strongly galvanized. Life truly hangs by a thread while we know not whether in any one of the attacks the nerve disorder may not take this fatal direction, instead of invading the recurrent laryngeals only. The superiority of morphia to bella- donna was unequivocal, a result which was not anticipated, on ac- count of the greater tendency of opium to cause tetanic phenomena. It is very possible that in another instance the result might be different, but it is as well to remark that in the fatal case of epileptic disorder recorded at p. 51 the attacks subsided under the adminis- 238 RESPIRATORY NEUROSES. tration of morphia. The doses given were certainly large, the strength of the bimeconate being about equal to that of tr. opii ; they produced however no trace of narcotism. This shows that the erethysm of the centres must have been considerable. The car- bonate of iron which was tried was certainly of no benefit, if not injurious. This result contrasts strongly with the good effect of tonics in the other case. It may be accounted for I think by ob- serving that the subject of the first case was a very weakly child, while that of the second was the reverse. The condition of the latter was more sthenic than that of the former. All this corrobo- rates what has been before said as to the difficulty of determining exactly the remedy suitable to an individual morbid state, and shows how the self-same symptoms may result from difi"erent pathological conditions. The attacks had indeed ceased before he was removed into the country, but the great improvement which ensued in his health makes it eminently probable that his subsequent immunity depended on the calming and toning influence of the purer air. Considerable intermissions had previously occurred, but had been followed by relapses. Romberg writes respecting the free intervals, " the first thing to attend to is the atmosphere and the diet." This is quite my own feeling, and indeed in all neuroses attended with a high degree of sensitiveness and excitability, and not depending on an eccentric cause, I look to the influence of a pure rather bracing air as the most sovereign remedy. Tonics are apt to prove too irri- tating and sedatives to lose their efficacy. In an able paper on this disorder (v. Brit. Med. J"., March 7th, 1857) Mr. T. Paget lays down the following directions for treatment with which to a great extent I concur. After removing all peri- pheral causes of irritation, whether dental, intestinal, or elsewhere seated, he contemplates the subjection of nerve excitement by means of narcotics as the most important object. " Upon the narcotic to be used, upon the mode of giving it, or the dose required, I need lay but little stress, especially since it is well known how varied is the susceptibility of individuals in reference to this class of medi- cines. Suffice it to say that the drug I have most used is opium ; that beginning with small doses and cautiously regulating them according to their efi"ect, I do not stop short of producing a constant drowsiness and some slight pallor, that when this state is obtained, the paroxysms decrease in force and frequency, the infant is calmly sleeping its day away, no longer devil-torn, nor are its friends racked with anxiety ; and that when the paroxysms have failed to occur for some forty-eight hours, which will usually happen in from three to six days, the drug is gradually withdrawn, the quantity taken off each dose being immediately restored if the attacks show the slightest disposition to encroach again. I may say also that to attain to the required effect I have usually been obliged to give to children 4 or 5 months pld (the age at which the disease most commonly perhaps ASTHMA. 239 invades) from 1 to 5 minims of tr. opii in a dose with 4 or 6 of sal volatile two or three times a day ; or if in enemata 5 to 7 minims." Asthma is by general consent acknowledged to be essentially a neurosis, though it is rare to meet with it in a pure form. Usually it is attended with more or less of bronchitis just in the same way as retinal hypereesthesia is with conjunctivitis, while spasm of asso- ciated muscles is a prominent feature in both cases. The view usually taken of the special seat of the neurosis is that it affects those branches of the vagi which are distributed to the bronchial muscles, and that the latter being spasmodically contracted seriously obstruct the access of air to the cells of the lungs. It would be expected according to this view that the chest would be rather diminished than expanded in size, and such appears to be actually the case. That excellent observer, Dr. Walshe, states that there is sinking of the epigastrium, and elevation of the diaphragm (evi- dently from the diminished mass of air in the lungs). Dr. Flint^ says that " if emphysema be not present, the volume of the lungs may be so reduced by the expiratory efforts as to diminish appreci- ably the clearness on percussion." It appears however that this is not a constant and invariable condition, but that it may be replaced by the opposite. Wunderlich^ describes one form of asthma as consisting in a gradual augmentation of the dyspnoea which reaches its maximum at the end of two or three days. At this stage the chest is almost motionless in spite of the most violent muscular efforts, the percussion resonance is everywhere preserved, and after many hours the limbs of the chest are extended downwards. The liver also descends, the heart is thrust into the epigastrium, and the thorax is excessively distended." Thdry^ also describes the thorax during the paroxysm as being in a state of the greatest distension, as in forced inspiration. The diaphragm however contracts some- times so forcibly as to depress the lower end of the sternum back- wards. Kidd^ and Sanderson' describe this state of great distension as that which is characteristic of asthma, though they differ as to the mode of its production. The former refers it to a tonic spasm of the muscles of inspiration ; the latter to a relaxation of the dilator muscles of the glottis, as well as of the contractile fibres of the lung tissue, in consequence of which expiration cannot be properly performed. There can be I think little doubt that the view held by the two last observers is too exclusive, and that except in cases complicated with extensive emphysema there is no notable if any dilatation of the chest in the earlier part of an attack of pure nervous asthma. That in the course of a prolonged fit the chest should become distended is quite intelligible if we consider that the inspiratory power is much superior to the expiratory, and I '^On Respirat. Organs," p. 897. 2 "Pathologie," III. 316. 3 Merkel's "Report on Asthma," Schmidt's " Jahrb.," Tol. cix. p. 229. 4 ''Dublin Q J. of Med Sc," May, 1861. 6 "Med. T. and Gaz.," May 16, 1863. 240 RESPIRATORY NEUROSES. that the air gradually accumulates in the lungs being locked up as it were by the bronchial constriction. Salter, who has most ably stu- died the whole subject of asthma, adopts the theory of bronchial spasm of nervous origin, and states that the chest distension is dependent on the demand for air, and is observed in all states of insufficient aeration of the blood. The circumstance that during the worst of an attack the expectoration is scanty or nil is tolerably good proof that the small arteries of the bronchial mucous membrane are con- stricted during this time, and adds to the probability that the bron- chial tubes themselves are in the same state. It must be admitted I think as pretty certain that hyperaesthesia of the sensory filaments of the vagi cannot be the essential pathological state, for this as we have lately seen induces, not spasm of the minute bronchi and ex- aggerated action of the inspiratory muscles, but violent action of the expiratory in cough, with more or less copious expectoration. The shifting of the dry rales heard during the paroxysm from one part of the chest to another affords some evidence that the smaller tubes are at intervals narrowed so as to produce such sounds and again relaxed. The depression, the chilliness of the skin, the small- ness of the pulse, the aqueous quality of the urine, remind one some- what of the cold stage of ague' in which, by the way, along with various spasmodic phenomena there is " distressed and anxious breath- ing." If the inspiratory muscles were primarily affected so as to keep the chest in a state of almost permanent inspiration, there is little doubt that the will would be able to interrupt occasionally this morbid action, and to procure every now and then a forced expira- tion, so that the used-up air might be expelled from the lungs. This however there seems no power to do. From these and other considerations, I am led to regard true asthma as a tetanoid disorder of the motor nerves of the bronchi, and as in great measure depend- ent like epilepsy on morbid excitability of certain nervous centres, which are probably located in the spinal rather than in the ence- phalic districts ; this I conclude from the absence of any tendency to general convulsions in the asthmatic paroxysm. No doubt there are many cases where the peculiar excitability would remain inope- rative except for some peripheral irritation, just as in epilepsy ; and there may be great varieties in respect of the relative importance of the central and peripheral causes ; the former, however, I hold to be the more essential and constant element of the malady. The necessity of a peculiar predisposition is fully as apparent in asthma as in epilepsy. The nature of this predisposition may vary very much, it may consist in a tendency to skin eruption, to gout, or rheu- matism, or hagmorrhoids, or periodic hemicrania, or uric acid deposits. All these as Trousseau states are affections which asthma may re- ' Thery says, "Agues run parallel with, or alternate with, asthma . . . . . the primary cause may determine both disorders." — Schmidt's " Jahrb.," vol. cix. p. 237. ASTHMA. 241 place, and which in turn may replace asthma. This diathetic ten- dency which so often leads to asthma is frequently derived from hereditary descent. The extraordinary capriciousness of asthma is notorious, and is certainly a matter of high interest and significance. It proves how wonderfully slight and subtle may be the influences ■which act with great effect on certain states of the nervous system. Were it not well ascertained how very slight a change in locality will make all the difference to an asthmatic, we should feel much disposed to consider the notion as the result of a morbid imagina- tion. This should be remembered by us in dealing with other and still more obscure neuroses. The influence of the withdrawal of light on asthmatics is remarkable. One of my hospital patients, a male, £et. 35, declared that "when it gets dark he is done alto- gether," and another, a female, set. 75, found her paroxysm come on at nightfall, whether this occurred early, as in the winter, or late, as in the summer. Trousseau^ mentions the case of an asth- matic who when his attacks came on had five or six moderator lamps lit in his room, and was immediately relieved. Though the neurotic character of asthma is, as these and many other facts show, extremely marked, yet it is clear that it difi"ers from many of the more common, and especially the sensory neuroses, in that it is not associated at least frequently or intimately with marked signs of nerve debility. On the contrary, as Mr. Pridham observes, asth- matics are for the most part gifted with extraordinary energy and talents. The admirable Trousseau, who acknowledges his infirmity in this respect, is an instance in point. The treatment of asthma is eminently that of a neurosis. It con- sists first in the removal of all causes of irritation, such as catarrhal inflammation of the bronchi, dyspeptic disorder, unwholesome diet, and unsuitable climate, &c., and secondly in the use of various appro- priate tonics and sedatives. The prophylactic management of asthma involves as one of its most important parts the selection of a suitable locality for the invalid's residence. This can scarcely be determined except by trial. It should be borne in mind that the air of large towns is in not a few cases more beneficial to an asthmatic than that of the country, and that where there is a tendency to asthenic bronchitis a relaxing climate is unsuitable. Though the averting of pulmonary catarrh is highly desirable, we must remind our patients that no amount of guarding against cold will protect them against the stroke of influenza, which by the way seems to me to be far the most frequent cause of catarrh ; and also that the best way of effect- ually resisting the morbific action of cold is to tone and fortify the system so that it may be well able to endure it. It is truly a re- markable thing how the same temperature that withers and destroys the feeble vitality of the two extremes of age, invigorates and in- creases the life of the strong and healthy. An old lady, however, ' "Clinique Med.," vol. i. p. 539. 16 242 RESPIRATORY NEUROSES. under my care told me once that she was "quite well and wound up" as long as a sharp frost continued in December; as soon as the thaw set in she got a cold, tracheal cough and expectoration. On the frost setting in again sharply she rallied and became more vig- orous. It was remarkable this year, 1864, how very general catarrhs became as soon as the frost ceased. Cold bathing or sponging, reg- ular outdoor exercise, a suflficient but not excessive amount of cloth- ing, avoidance of damp, chilling draughts when sitting still, are the main points to be observed by the invalid who is fearful of taking cold. Of course, in every case judicious adaptation of general rules to the individual condition is essential. The importance of a duly regulated diet is well known, and has lately been especially illus- trated by Mr. Pridham.^ He restricts his patients at first to two ounces of fresh meat with as much dry bread for dinner at one P. M., and the same for supper at seven, allows a cup of tea with cream and dry bread in the morning, and for drink weak brandy or whiskey and water, which is not to be taken till three hours after animal food. Rest is also enjoined for the same period, though air and ex- ercise are recommended. Three grains of extr. conii are given four times a day, just one hour before each meal. As the symptoms im- prove the diet is increased, though it is still very spare and simple. The rationale of this proceeding is very evident; it is manifestly well adapted for patients who betray any symptoms of disordered digestion or assimilation. As there seems no doubt that the ma- teries morbi of gout may give rise to asthma, so it is very possible that unhealthy products of digestion may act in a like manner. In most of Pridham's cases the urine was habitually loaded with lithates, indicating an excess of acid passing oflF by the kidneys. The more our pathological knowledge increases, the more do we find that many different causes are capable of producing the same effects. Prid- ham professes to treat in the above way only what he terms dys- peptic asthma, though he seems inclined to extend the significance of the term rather widely, as he says that he is convinced that an asthmatic person can never with impunity eat and drink as other people do. An inveterate asthmatic who was once under my care told me, however, that, though he was obliged to be careful in his diet, yet he could go out to a dinner party and eat and drink like any one else and not be the worse for it. He also found, as indeed occurred while I had him in view, that when he got bronchitis the asthmatic attack ceased. Trousseau gives an exactly similar case. Such instances show clearly the essential difference between inflam- matory catarrh and asthma. Gymnastic exercises, riding, sawing, bowling, have been praised for their good effects ; and, as tending to diminish excitability and increase tone and strength, they are likely to be useful. Compressed air has recently been introduced as an ' "Brit. Med. J.," June 9th, July 28th, Sept. 1st, 29th, Nov. 17th, Dec. 29th, 1860. ASTHMA. 243 agent in the treatment of various pulmonary affections, including asthma. Sandahl in his paper* states that of fourteen cases of asth- ma and pure simple pulmonary emphysema all were improved, and twelve as far as could be made out had experienced no relapse. Of seventy-seven who suffered with asthma, emphysema, and chronic bronchitis, fifty- seven were improved and twenty either doubtfully or not at all. From Vivenot's observations'^ it appears that the effects on the system are slowing of the pulse and the respiration, diminution of the pulmonary and cutaneous exhalation, increase of the urinary secretion, and prevention of congestion in the parts on which the air acts. It may reasonably be expected that benefit would result from these baths in all cases of catarrhal affection of the air-passages, but in pure spasmodic asthma it is not very apparent how they could act beneficially, nor does there seem sufficient evi- dence to prove that they have done so. M. Beau^ finds sulphuret of potassium baths not only to relieve the attacks of asthma, but to prevent their recurrence. Each bath should last twenty minutes, and thirty should be taken, one every other day. The temperature should be 86° F. Certain tonics seem to be of real use in not a few cases. I have found arsenic sometimes of much advantage, admin- istered in doses of "i^iv — v of Fowler's solution ter die. It may be given with ammonia and tr. camph. co., or alone, or with an or- dinary cough mixture, according to circumstances. We should assure ourselves before giving it that it is likely to be tolerated by the stomach. When there are indications of gastric as well as of bron- chial catarrh, nitric or muriatic acid is preferable in combination with acid, hydrocy. dil. and tr. calumb. When there is bronchial catarrh alone, atropia with or without nitric acid is a valuable remedy. I have had a case recently under my care which has terminated very satisfactorily under atropia gr. yi^ ter die, and tannin with Canada balsam in pills. Atropia is a remedy on which I feel much inclined to rely both from experience of its power as a sedative, and from the observations of Dr. Williams as to its abolishing the contractility of the bronchi, which is just what is desirable in asthma. Cannabis indica has occasionally proved very useful, gr. | doses of the extract immediately checking the spasm. In one case where asthma super- vened upon phthisis great relief was afforded by the subcutaneous injection of liq. opii sed. ^L x into the left front of the chest. M. Courty^ has also obtained very good results from subcutaneous injection of atropine (gr. -^ thrice repeated) in the vicinity of the left vagus nerve. Dry cupping should be persistently employed as long as there are signs of congestion of the bronchial mucous mem- brane. In some cases pot. iod. proves very beneficial. With regard to the shorter and severe paroxysms I can do little more than ' Schmidt's "Jahrb ," vol. cxx. p. 178. 2 Ibid., vol. cix. p. 33-5. * "J. de Med. et de Chir. Pratiq.," vol. xxxiii. p. 440. * "Gaz. Med.," Nov. 1859. 244 RESPIRATORY NEUROSES. enumerate the various remedies which have been found efficient. Ice pills according to Romberg often afford instant relief, and inhalation of sulphuric ether or chloroform may be very serviceable. Smoking tobacco, or stramonium, or a compound of the latter with belladonna, will sometimes quell the spasm. Ipecacuan emetics may be given for the same purpose. Opium combined with spt. £eth. s. co. has in some cases a good effect. Nitre paper should not be forgotten, made according to Dr, H. Salter's formula by soaking red blotting paper in a solution of giv of pot. nitras in aq. Oss. In some in- stances Ducros' medication or a modification of it is beneficial. He brushes the posterior wall of the pharynx with a strong solution of ammonia, liq. ammon. + aq. aa 5J. The first time that Trousseau tried it he thought the patient would have died suffocated. He states, however, that " employe dans une juste mesure il a rendu de reels services." Probably M. Faure's plan is preferable. He puts Sss of liquid ammonia in a bowl, and desires the patient to inhale the vapour, taking care, however, to close the nostrils. The inhalation is to be continued for fifteen minutes, and to be repeated four times a day. Trousseau relates that the captain of a ship was always exempt from the paroxysms while his vessel was loaded with guano, or he was staying at the gathering grounds. Various stimulants are occasionally beneficial, strong coffee, tea, ammonia, and alcohol. Dr. Salter^ has recently published some remarkable evidence of the power of very large quantities of the latter to subdue paroxysms of the disease which had proved refractory to all other measures. In- toxication was not necessarily produced. The efficacy of alcoholic and other stimulants I believe to depend on the circumstance that their action on the nerves or nervous centres replaces advantageously the morbid action which previously affected them. We have here another instance of the affinity between spasm and paralysis, both being advantageously treated by the same means. To prevent recurrences. Trousseau advises a compound medication consisting of ten days of small doses of belladonna, as many of tur- pentine, and the remaining ten of the month of arsenical cigarettes, besides a sixty grain dose of powdered calisaya bark in coffee every ten days. This plan must be followed out a long time and very exactly. Sneezing and hiccup are two minimum disorders as they usually occur, but they occasionally develop themselves to the dignity of a disease. Romberg cites several instances of the former occurring either in his own experience or in that of others. It is met with occasionally as an accompaniment of hooping-cough, and of ver- minous disorder, as well as in the so-called hysterical state. Mosler relates a case,^ in which a scrofulous female was computed to have sneezed 50,000 times in eighty hours, and the neighbourhood was alarmed ! She was amenorrhoeal, and the disorder returned a month » "Lancet," Nov. 14, 1863. ^ . "Assoc. Med.

Dr. Christison speaks very decidedly as to the non- increase of renal irritation in the cases where he has administered it for the relief of the dropsy of Bright's disease. Tannin may be taken as representative of the class of astringents. It seems to me certainly doubtful whether it has any direct action on nervous tissue, while that it exerts such on the smaller vessels is tolerably certain. It probably renders their membrane more firm and resistant, and therefore less distensible by the blood and perme- able by exudation. It finds its opportunity in asthenic forms of in- flammation and congestion, where it reduces the hypersemia by con- tracting the vessels, shrinking up and obliterating those which have been morbidly developed. In a case of inveterately relapsing cor- neitis of both eyes producing very great impairment of sight, I ulti- mately obtained complete recovery by giving gr. xxx of tannin ter die. I think it is quite possible that the nervous tissue may be affected by the astringent in an analogous way to the vascular, ren- dered less mobile and excitable. The beneficial effect of alum in lead colic, which can hardly depend on removal of the lead from the system, points to some influence of this kind. In any condition where nervous disorder might be increased or maintained by hyper- semia tannin would probably be useful. On this ground its utility may be explained in some cases of epilepsy. Its chief advantage in such and in similar disorders depends on its having less tendency to cause irritation than most other tonics. Sulphuric and Nitric Acids have certainly some claim to be re- garded as toners of vaso-motor nerves. They cannot be supposed of course to act in their original form on the parts they influence, as their acid quality must be lost the moment they enter the circulation. They cannot be mere astringents like tannin. When sulphuric acid restrains a choleraic purging, or a colliquative sweating, these effects must surely be produced through the nerves that regulate the arteries of the internal and the external teguments. Its special nervine action is attested by the following quotation from Dr. Pereira •} " No remedy is so successful in relieving the distressing itching, formi- cation, and tingling of the skin as diluted sulphuric acid taken in- ternally." Nitric acid is certainly a remedy of considerable efficacy in catarrhal affections both of the bronchi and intestines, and it has further this special indication of its nervine operation that it is often very serviceable in the spasmodic period of pertussis. To those who are impressed like myself with the great concernment of the nervous system in all cases of malarial fever, it will not be without signifi- cance that nitric acid has been found a valuable remedy, in these disorders, in some cases surpassing quinine.^ It is very useful also in enlarged spleen.

Moliere's quiz at physicians on this score is almost as appropriate now as at the time he wrote. There can, I think, be scarcely a more glaring instance of the neces- sity which exists for careful research into the modus operandi of remedies. Taking our common experience of the eifects of opium, we know that it acts as a soporific, as a calmer of pain, and as an arrester of intestinal and other secretions and morbid profluvia, even of some hemorrhages. Graves gives a case in which obstinate bleed- ing from the gums was arrested by opium, v. Clin, Med., p. 272. Stewart relates some cases in which opium was given in very large doses to females who were syncopic, and almost dying from uterine hemorrhage with very great advantage, v. Med.-Chir. Trans., vol. iv. p. 366. Further we know that in certain constitutions it has a stimulating influence on the brain, manifested both in greater activity of the intellectual functions, and in a greater capacity of enduring fatigue. This stimulating eifect when excessive may be succeeded by depression and sopor. In some inflammatory diseases, as in sclerotitis and peritonitis, opium decidedly checks and subdues the hypersemia and tendency to exudation. The action of the drug on the cutaneous nerves seems to be rather uncertain, it does not seem by any means to cause diaphoresis frequently. Nay, even Dover's powder I have found in accordance with Deschamps'' recommendation materially to check the night-sweats of phthisis. The reading of these various facts is sufficiently obscure; it is not easy to refer them to any one general principle. Perhaps it is premature to make the attempt in default of accurate observations upon animals, yet as they are not by any means aff'ected by the drug in the same degree in which human beings are, we cannot avail ourselves to any great extent of this mode of inquiry. Muller indeed has shown^ that opium exerts a local influence on the nerves, destroying their excitability, and that this influence is not propagated either towards the periphery or cen- tre. This is true both of the cerebro-spinal and sympathetic nerves. It may be questioned how far such a proceeding as immersing a nerve dissected out from the tissues in a solution of opium fairly represents the action of the drug when it is diff"used through the whole mass of the circulating blood. However, if we accept the above experiments of Muller, it seems reasonable to refer the sopo- rific and pain-allaying property of opium to a sedative action exerted on the nerves or nervous centres. On this view we should expect that the nerves generally would be similarly affected, that the face would be flushed in opium poisoning, that hemorrhages and inflam- mations would be aggravated, and diarrhoeal and other fluxes in- creased in consequence of paralysis of the vaso-motor nerves of the facial, intestinal, and other arteries. As the reverse is the case we > "Gaz. Med. de Lyons." Jan. 1861. 2 MuUer's "Physiol.," vol. i. p. 679. ■ 324 * REMEDIES. meet with a difBcultj, wbich we must try to remove. It can scarcely be supposed that opium acts in a contrary way on the sympathetic to that in which it does on the brain and cord. It stills pain alike in parts supplied by either set of nerves. It might be imagined that opium acted on other tissues in an analogous way to that in which it affects the nervous, rendering them as it were torpid, and disinclined, or inapt to function. This would explain the arrest of secretions, and perhaps of exudations, and of inflammations, but leaves quite unaccounted for, or rather is contradicted by, the stim- ulant action of opium on the brain, its power of preventing fatigue, and of arresting hemorrhages. Two things are most necessary to be regarded in speculating on the modus operandi of opium, viz., the amount of the dose, and the individual idiosyncrasy, or the state of nervous power. According as these vary its effects vary extremely. It appears that the larger the dose, eceteris paribus, the more speedily and decidedly sopor ensues, while small doses are more apt to cause excitement. Small doses also are quite adequate to control diarrhoeal exudations and to "lock-up" secretions. It may be supposed, it appears to me, with much probability that the apparently different actions of opium depend very much on the cir- cumstances whether it acts chiefly on the cerebro-spinal or sympa- thetic systems, a difference which may reasonably be ascribed to original diversities of constitution. The chief action of opium in moderate doses is that of a stimulant or toner to nervous tissues, but in the majority of individuals it acts more on the sympathetic than on the cerebro-spinal system. By stimulating the vaso-motor nerves it produces contraction of arteries, and thus lessens the flow of blood to various parts. Hence the skin of the face and head in opium narcosis becomes pale and cool, while the brain more or less deprived of blood lapses into sopor. Hence also hypergemias, hemorrhages, and morbid exudations are arrested, and even natu- ral secretions restrained. These instances seem to me almost con- clusive ; if opium did not contract arteries how could it arrest a uterine hemorrhage ? The calming of pain by the local application of opium, as in subcutaneous injection, may be explained according to the view I adopt if we bear in mind what has been advanced as to the essential character of neuralgic pain for the relief of which opium is most efficacious. The suffering nerves being in a state of vital debility are restored to a healthier state by the action of a stimulant. I have seen the subcutaneous injection of morphia pro- duce immediately a good-sized patch of redness with two or three red elevations like longish wheals. Mr. Simon says, " Opium is not an anaesthetic except by the production of stupor." The mental excitement and the prevention of fatigue may be accounted for by its exerting a stimulant action on the brain and spinal cord. The chief objection to the above view is that opium if it acts specially on vaso-motor sympathetic nerves ought to dilate rather than contract the pupil. The radiating fibres of the iris, which are made to con- REMEDIES. 325 tract by galvanizing the cervical sympathetic, ought to be similarly Effected when opium is administered. It is very possible that this would be the case ,did not the motor nerves of the circular fibres pass through, and probably receive additional fibres in the lenticular ganglion. This nervous centre must be regarded as belonging to the sympathetic, and consequently the nerves proceeding from it will be affected by opium in the same way as other sympathetic nerves are. The pupil is therefore contracted. Unless it be admitted that the gray matter of the ciliary ganglion influences the nerves which proceed from it, it is not easy to imagine what can be its purpose. If the action of opium could be limited like galvanism to the sym- pathetic filament proceeding to the nasal, or to the lenticular ganglion, it might produce dilatation. As it is, however, the far more power- ful muscular and nervous apparatus which effects the closure of the pupil overrules the other. A case recorded by Dr. Baly in his trans- lation of Muller's Physiology, vol. i. p. 828, may be noticed here. The third nerve of one eye was paralyzed, the pupil was slightly dilated and perfectly fixed, the strongest light causing no contraction, although the vision was perfect. The adjusting power of the eye was lost or much impaired. Now in this case the pupil was not much dilated because the gray matter of the lenticular ganglion still kept up an influence on the motor nerves, but the iris could not be influenced through the retina, because the communication of the ganglion with the third nerve was interrupted. Belladonna, on the other hand, dilated the pupil further by paralyzing the ciliary gan- glion. There is no doubt that the optic and the third nerve constitute the nervous apparatus essential to the main movements of the iris, and the dilatation can be accounted for under ordinary circum- stances simply by the unopposed action of the straight fibres, most of which may be merely elastic tissue. The sympathetic fibres are probably as in other situations chiefly distributed to vessels, and take no important part in the movements of this muscular curtain. Clearly full dilatation of the pupil occurs under circumstances which seem to exclude all stimulation of any nerve, as in chloroform, narcosis, and fatal syncope. A second objection which may be made is that copious sweating occasionally occurs in opium poisoning, and even from moderate doses of the drug. This looks more like relaxation of vessels than contraction. To this it may be replied, that copious sweating is a common result of any cause which powerfully depresses the nervous system ; it occurs in apoplexy, in profound debility of malarious origin, and in sudden embolism of the pulmonary artery. It may therefore well occur in fatal opium narcosis, where the brain is para- lyzed for lack of arterial blood. As to the diaphoretic action of ordinary doses it may be explained on the following grounds. All glands, as Bernard shows, have their motor nerves, stimulation of which excites them to active function. Now retaining the view that the primary action of opium is stimulant, it is quite conceivable thac 22 326 REMEDIES. in some parts it may stimulate the gland-motor moi'e than the vaso- motor nerves, and thus promote instead of suppressing secretion.* Individual peculiarity is probably largely concerned here ; thus cats are, I believe, invariably profusely salivated by a dose of opium, while I scarcely have ever heard of such an occurrence in man ex- cept the case mentioned by Pereira.^ A third objection may be raised from the circumstances that opium produces in some persons an increased flow of urine, as especially observed by Dr. Woodward.^ I have several times observed this, but have always seen that the secretion was pale and aqueous just like hysterical urine. It is very difficult to say what condition of vessels coexists with this kind of renal secretion, but I doubt very much whether it is one of arterial dilatation. Most probably some peculiar change is produced in the homogeneous membrane of the Malpighian capillaries, affecting their filtering action. The slower and diminished breathing observed in opium narcosis depends probably on a state of torpor of the respira- tory centre, itself the result of a diminished flow of arterial blood. The same condition of the hemispheres accounts for the coma, the brain being, as lately shown by Durham^ and Bedford Brown, ^ more or less ansemic during sleep. The occasional occurrence of con- vulsions may with our present knowledge be reasonably ascribed to the cerebral anaemia. That these various phenomena depend princi- pally on arterial contraction seems to me still more probable from the remarkable restorative efi'ect of belladonna, which has now been observed in several cases.^ If the vital power of the tissues them- selves was deeply injured by the one drug, they could hardly so soon resume their action under the influence of the other. In one re- corded case, v. Brit, and For. Med.-Chir. Rev., April, 1858, the pulse was scarcely perceptible, though the heart's beat was strong. In another mentioned by Dr. J. W. Ogle, Med. T. and G-., Oct. 3, 1863, the surface was icy cold. Both these phenomena are mostly results of over-excitement of vaso-motor nerves. While I cannot but attribute the chief part of the operation of opium to its influence on the vaso-motor nerves, I think also that it may in large doses (like alcohol) act paralyzingly by over-stimulus on the encephalic nervous centres. Indeed both agents have in many respects the same eff"ects. Thus both in small or moderate doses stimulate the brain, in larger produce sopor but leave the respiratory centre efficient, and in still larger doses cause fatal coma and collapse. In all cases a very great deal depends on the degree of impressionability of the nervous force, and on its condition in different parts. If the vaso-motor nervous apparatus be very sensitive, as in young children, the arteries are very readily occluded, and coma ensues, while in older persons the gray matter of the hemispheres will be first affected in a way of 1 "Mat. Merl.," vol. i p 708. 2 "Boston Med. J.," vol. Isv. p. 108. 3 "Guy's Hosp. Reports," vol. vi. p. 149. « "Amer. J. of Med. Sc," Oct. 1860. 6 Ibid., Jan. 1852. REMEDIES. 327 excitement, and it •will require a large dose to produce a soporous state. In states of cerebral excitement it may require an almost poisonous dose of the narcotic to produce sleep. The action of the heart is commonly increased by moderate doses of opium, or at least in nowise depressed, but after poisonous doses it becomes very feeble and failing. This results partly from the contraction of the coronary arteries admitting an insufficient supply of blood to the muscular tissue, and partly from the same state of the bloodvessels of the cardiac centres, in consequence of which they cease to supply the heart with nervous influence. Belladonna may be ranked as the physiological opposite to opium. In full doses it causes extreme flushing of the face and head with great distension of the veins, numbness of the face, dimness of sight or even blindness, confusion of head, delirium sometimes attended with great excitement, dryness of the mouth and throat, extreme dilatation of the pupils, and often an erythematous eruption. The chief points of contrast in its action as compared with that of opium are the state of the pupils, the deep flushing of the face, the delirious excitement, the acceleration and sometimes increased strength of the pulse, and the hurried breathing. Sopor is generally consecutive to delirium, and is often replaced by wakefulness. Therie can be to my mind but little question that the deep congestion of the skin of the face and head, the delirium, and the cutaneous erythema depend on arterial dilatation and increased afflux of blood in those parts. In one case the skin of the face had been as red as blood, but had quite returned to its natural state twenty-two hours later when I saw the patient ; delirium had existed along with the congestion, and had disappeared with it. It is impossible to consider such temporary congestion as the result of tissue irritation, the effect of a mustard poultice would not have ceased so speedily. The acceleration of the pulse may reasonably be ascribed to paresis of the cardiac branches of the vagi, or of the vaso-motor nerves of the coronary arteries, the first being the more constant occurrence, and the second probably being added, when the pulse is not only rapid, but strong. The accelerated breathing is the result partly of free blood-flow through the medulla oblongata, partly of the increased cardiac action. The increased heat of the skin, the erythematous eruption, or the perspi- ration, all which have been observed, are easily explicable on the view of vaso-motor nerve paralysis. The evidence in favour of the pain-calming action of belladonna is very decided. Trousseau does not hesitate to affirm as the result of very numerous experiments that of all the remedies employed against the symptom pain there is none which seems more constantly efficacious than belladonna. He admits, however, the superiority of opium in internal pains. The blindness is probably in part dependent on paralysis of the ciliary muscle which is afi"ected just in the same way as the iris, and through the medium of the same nerves. The numbness of the face and the weakening of muscular power are also indications of diminished vis- 828 REMEDIES. nervosa. Botkin^ and Michea^ both agree that belladonna destroys the excitability of the nerves, affecting the motor before the sensory, and lastly the cerebral hemispheres. The peripheral extremities of the nerves are first affected. The heart's action ' was rendered ■weaker and more frequent, and the pressure in the arteries dimin- ished. Thus most of the phenomena produced by belladonna seem to be satisfactorily explicable on the view of its occasioning paresis of nervous tissue generally and especially of the vaso-motor nerves. There are, however, two very constant results of its action which seem to be of a different kind. These are the dryness of the mouth and the throat and the dilatation of the pupil. The first seems to imply a contraction of the vessels supplying the mucous membrane and the salivary glands effected doubtless through stimulation of their nerves. I have examined the throats of various persons under the influence of atropine, but have not been able to satisfy myself that there was any marked dryness. I am therefore much inclined to regard the phenomenon in question more as a dyssesthesia than as a real arrest of secretion. If, however, it actually occurs, it may be explained on the view of its paralyzing the gland-motor nerves, while opium sometimes does the contrary. The dysphagia and aphonia which sometimes occur are certainly paralytic phenomena, and so in accordance with the general mode of action. The question as to the action of atropine on the pupil has been admirably studied by Dr. Harley,^ who considers it proved, (1) that atropine does not dilate the pupil by stimulating the sympathetic as galvanism does, and (2) that it does not do so either merely by paralyzing the third nerve, supplying the circular fibres of the iris. He is most inclined to adopt Ludwig's view that the drug acts directly on the radiating fibres, and relates an experiment showing that a recently removed eye immersed in solution of atropine comes to have the pupil fully dilated in some hours, while the companion eye placed in water shows no such change. It is a very difficult question to decide completely, but after a careful perusal of the facts recorded I think there is little doubt that atropine does not stimulate the cervical sympathetic and thus produce contraction of the radiating fibres of the iris. The chief evidence is as follows: — (1) Atropine applied for twenty-five minutes to the upper end of the divided sympathetic does not cause the contracted pupil to dilate as g;ilvanism does. (2) When the third nerve is divided the pupil dilates immediately and permanently, and the dilatation is not in- creased by atropine ; the cervical sympathetic being now divided, the pupil contracted to one half, both sets of fibres being paralyzed. (3) The pupil being fully dilated by atropine the sympathetic on that side was divided, the ear became warm, but the pupil remained fully * Virchow's "Archiv.," vol. xxiv. p. 83; 1862. 2 "Ann. de Therap.," 1864, p. 8. 3 -Edin. Mjd. J.," 1856, 1857, p. 431, and p. 705. REMEDIES. 329 dilated for three days, afterwards gradually contracted, and was completely so by the ninth day. (4) Sympathetic divided on one side, the contracted pupil made to dilate at first to half its extent with atropine, 'subsequently by long-continued application made to dilate completely. The general bearing of these facts seems to me to be that atropine does not stimulate the sympathetic, but that it acts on it as it does on other nerves, paralyzing therefore the ciliary ganglion and nerves, as well as the third. The effect of atropine on the ciliary muscle should be taken into account. This, as having but one set of fibres, is a simpler structure, and its action can more easily be determined. Atropine certainly paralyzes it, and so also does disease of the third nerve. It therefore seems probable that atropine acts in a like manner upon the iris with which it is asso- ciated. As to the direct action of atropine on the iris it seems diffi- cult to understand how it can affect one set of fibres without the other, the two being supplied absolutely by the same capillaries. It is very possible that the contraction of the pupil produced by division of the sympathetic depends on an increased flow of blood to the iris, and on an exaltation of the vital properties of its circular fibres, which then contract with greater energy, v. p. 27. When the divided sympathetic is galvanized dilatation ensues because the vital power of the constrictor is now diminished, and so it is less capable of action. The radiating fibres meanwhile, though similarly affected, meeting with less resistance shorten by mere passive contractility. Paralysis of the sympathetic makes it more difficult for atropine to dilate the pupil because of the increased energy of the constrictor, so that a greater amount of the drug is required to overcome its action. When l)ella donna applied to the skin of the forehead dilates the pupil of that side only it is difficult to suppose that it is absorbed, or that it directly aff"ects the ciliary nerves. What is certain is that it must act on the sensory filaments of the ophthalmic division of the fifth, and through these it is probable that a reflex action of an inhibitory paralyzing character is communicated to the third nerve. ^ Botkin's experiments seem sufficient to prove that it cannot act as a stimulant as Wharton Jones and others think. I have examined the web of the frog under the influence of atropine, both when applied locally and injected subcutaneously, but I did not observe that the arteries were notably affected. The circulation is very apt to be afi"ected by • Tlie above had been written a long time before I met with the following passage in Simon's Led. on Pathology, p. 219. " An aneesthetic agent operating on the pe- ripheral expansion of the fifth nerve produces the negation of, excitement in its centre ; this condition diffuses itself to the motional centre of the iris, and as excitement would have shown itself in contraction of the pupil, so the opposite nervous condition evinces itself in expansion of that aperture. Where the reactivity of the spinnl cord is very highly excited a peripheral surface may by the influence of belladonna be ren- dered incapable of provoking reflex movements. Thus, for instance, if a frog be ren- dered tetanic by opium or .strychnine, any contact of its cutaneous surface will pro- duce universal spasm ; if either before tliis poisoning, or subsequent to its manifes- tations, one limb of the animal be plunged into a solution of belladonna, no mechanical irritation of that portion of the body will cause the tetanic convulsion." 380 ■ REMEDIES. movements of the animal which possibly may have been a cause of error. The state of brain in which belladonna is occasionally useful- as a soporific is where there is violent excitement and wakefulness, with a contracted pupil. Hyoscyamus appears to be chiefly a simple and direct cerebral sedative. Of its calmative and hypnotic action I have no doubt, but it produces no other distinct effect when given in ordinary doses. In poisonous quantities it acts somewhat like belladonna. The nar- cotic effect of both drugs is, I believe, due to direct action on the nervous centres. Aco7iite is certainly of great value as an external application in cutaneous hypersesthesia, and in some neuralgias, but I am shy of administering it internally. It may be used, however, in various conditions characterized by sthenic nervous excitement, certain pyrexise, neuralgias, and headaches, but its effect should be carefully watched lest it induce perilous depression of the heart's action. The dose at first should not exceed y\x of the tincture (PA. Brit.) ter die. Cannahis Indica has certainly an influence on the brain, producing not unfrequently a kind of intoxication or delirium. There seem to be great individual differences in respect to the tendency to be thus affected. In most persons an ordinary dose produces no notable effect, but in some the cerebral disturbance, and the delusions usually of a pleasing kind are very considerable. The primary stimulant action is succeeded after a time by a sedative, but no actual narcosis appears to be produced. There is evidence that cannabis has a tranquillizing influence on the spinal cord in tetanus, but it is not to be relied on for producing this effect, and does not seem comparable in this respect to aconite. My own experience is quite corroborative of Dr. Clendinning's that it has a decidedly sedative effect in the cough of bronchitis and phthisis. Dr. Tilt says it is a wonderfully useful drug to quell neuralgia or mental excitement. In hysterical derangement. Dr. Forbes Winslow finds that the tincture will occa- sionally allay the excitement and produce sleep more rapidly than any other form of sedative. Fronmuller finds that it produces a more natural sleep than any other narcotic, and that its action is not attended with any unfavourable after-effects. Sir R. Martin finds it very effectually to arrest the vomiting of hysterical females, and my own observation leads me to the same conclusion. Dr. Reynolds' experience of it is peculiar; he says* it is useless in mere functional, psychical, sensory, or motor disorders, without demonstrable organic change ; on the other hand, it is essentially beneficial in cases of con- gestion, softening, meningitis, or hemorrhage. The drug appears to diminish the over-activity of the nerve centres without disturbing the animal or vegetative functions. On the vaso-motor nerves I have not observed it to have any action, but Dr. Churchill speaks of it as 1 "Arch, of Med.," Jan. 1861. REMEDIES. 331 a valuable remedy in menorrhagia, classing it along with ergot of rye. The general result seems to be that it is principally a cerebral sedative, wbich is not appropriate to conditions of sthenic excitement, but rather to such as manifest debility and depression with hyper- sesthesia. Dr. Forbes Winslow gives a hint which is worth remem- bering with regard to the employment of sedatives generally. This is that cases which are intractable to separate remedies, Avill yield to a judicious combination of several. This is probably the secret of the success of the nostrum, chlorodyne. Hydrocyanic acid is familiar to us all as a useful sedative in gastric and bronchial irritation. It is evidently a nervine, but its modus operandi is not at all clear. In poisonous doses it produces tetanic convulsions and insensibility preceded by faintness and gid- diness ; the pupils are dilated, the pulse is small or imperceptible. In a good-sized young dog whom I injected with two t^^xxx doses of acid, hydroc. dil. subcutaneously at about ten minutes' interval the effects were as follows. He was prostrated in a few minutes, lay quiet with deep but infrequent breathing, and quick but feeble pulsa- tion of the heart, whose sounds were just audible. After the second injection the breathing became slower, and the heart's action feebler, and so he died very gradually in about twenty minutes from the first introduction of the poison. A stimulus to the cornea caused con- ^ traction of the orbicularis palpebrarum from seven to ten minutes before death, but not about four minutes later. At the autopsy made two hours after death the limbs were not rigid, the lungs were moderately congested, the heart was well and firmly contracted, its tissue remarkably firm, the cavity of the left ventricle almost quite obliterated, that of right small, but little blood in either, coagula in both auricles. Brain decidedly pale. From this it almost appears as if the heart's action had been arrested by over-stimulus of its nerves, tetanizing it. Perhaps convulsions and insensibility are pro- duced by similar tetanizing of the cerebral arteries. Such, however, are the effects of over-doses, and they do not throw any light on the results of ordinary ones. I believe we must for the present be con- tent to think of the drug as a direct sedative to nervous tissue. As such it has been used lately with great success by Dr. K. McLeod in cases of insanity attended with excitement. There is some evidence that the inhalation of Oxygen gas diluted, in the proportion of from 2 to 12 per cent, for small doses, and to a very much less degree for large doses, has a beneficial effect in various disorders, among which some neuroses may be reckoned. One of my own patients declares that he was restored by this means from a state of extreme depression in a marvellous way. Dr. Birch, ^ who has had the principal share in bringing this remedy forward, does not recommended it in nervous hypersesthesia, or chronic cases of extreme debility and spanaemia. He has found its good effects most ' "Brit. Med. J.," Dec. 24, 31, 1859. 332 REMEDIES. decided " in persons of a gouty or strumous habit, or otherwise in a state of general malaise^ with shiggish circuhition, either constitu- tional or superinduced by an atonic and oppressed condition through over-feeding and other luxurious habits." In some cases improvement coincides with critical discharges of retained excrementitious mat- ters. Mr. Hooper' records an intractable case of neuralgia of the sole of the right foot which was cured after much other medication had failed by the inhalation of oxygen. The patient was a labourer, set. 40, the whole foot was exceedingly hot, the agony beyond de- scription. No mention is made of gouty tendency. During the in- halation the urine became increased in quantity, and loaded with urates and phosphates. It seems probable that the remedy may be useful in cases rather of indirect than of direct depression. The operation of Oold on an ordinarily vigorous system is, as we have seen, tonic and invigorating, v. p. 31 et seq. It increases ner- vous power and specially excites the smooth muscular fibres of arteries and of the skin, as well as the nerves influencing them. Catarrhal affections are much more prone to ensue on the super- vention of a thaw than during a sharp frost. In its greater degrees, and in feeble states of system it is often depressing, partly we may believe by obstructing the free flow of blood through the arteries. The suppression of the catamenial discharge by the application of cold to the feet, of hgemoptysis by ice to the chest, and the bene- ficial eff'ect in cases of cerebral hypersemia of cold to the scalp in- * dicate I think plainly that cold acts through the incident nerves in a reflex manner upon the vaso-motor, and causes arterial contraction. We shall see presently that heat has just the opposite effect. It seems to me very probable that the extreme drow^siness which is pro- duced by intense cold depends on a want of a due supply of arterial blood to the brain, the congestion which is so often observed is pro- bably chiefly venous, and dependent on the mode of death, viz., by coma. The paralyzing action of cold in certain states of nervous power has been already alluded to, v. p. 188, and forms a good ex- ample of inhibitory action. It may aff'ect musculo motor or vaso- motor nerves, and in the latter case may if the vital power is weak originate actual inflammation by the hyperemia produced. The toning anti-neuralgic influence of dry cold is well shown in the fol- lowing case. No. 185. — W. L., 8et. 32, a healthy man.

The action of moist ivarmth, whether applied by warm baths or in any other way, is worth considering. It may be stated (1) that it is generally soothing and comfortirrg to sensory nerves in a state of neu- ralgic suffering, as for instance in the headache of influenza, and in the case of tic douloureux recorded at page 185, but not so constantly in the pain of inflammatory congestion, which, as in the case of a burn, is often arrested by cold. However, there is good evidence that in these same affections, even when very severe, moist warmth may be one of the best means that can be employed. Mr. Windsor' says, " Many years since we convinced ourselves by a series of com- parative experiments that there was no treatment for the collapse Avliich generally accompanies severe burns so eflScacious as th^ warm bath. In our cases the pain at once disappeared, and sometimes did not return, the pulse improved, and the countenance lost its anxious and sunken case ; the bath, however, was never continued for more than an hour." He thinks this treatment would often save life. Hebra relates a case of severe burn, the subject of which nine days after its occurrence was suffering intense pain, and could neither stand, sit, nor lie down straight. She was placed in a bath at 99.5° F., and an hour later she could stretch her legs, and the pain had dis- appeared. In forty-eight hours the pulse fell from 120 to 80, the thirst became less and the appetite increased. She remained alto- gether 604 hours in the water, the temperature of which was grad- ually lowered to 88° F., and recovered well. The beneficial action of cold in inflammation depends on its keeping the arteries con- tracted, and the part aneemic, if it does not efi'ect this it is rather irritating. (2) Moist warmth seems to abate the tissue irritation, the attractive 7iisics, which constitutes the essence of sthenic inflam- mation, causing afflux to and arrest of blood in the part independent of arterial dilatation. In a case of very aggravated psoriasis under my care the skin was paler after an hour's packing in a wet sheet than at any other time. The beneficial eifect of poultices and fomentations on inflamed parts, including the viscera of serous cavi- ties, depends chiefly on this sedative action on the tissue, which ex- tends even to the deeper parts. (3) I think we may be pretty sure that moist warmth applied to the cutaneous surface through its action on the afferent nerves and nervous centres relaxes the nerves and vessels of internal parts. A female, whose catamenia returned too frequently, informed me that soaking her feet in hot water would bring on the discharge at any time. The common prescription of a warm hip bath in amenorrhoea probably acts on the same principle, as otherwise it would be more likely to determine a flow of blood to the cutaneous surface than to the uterus. The benefit of a warm bath in children's convulsions probably depends on its inducing re- 1 " Syd. Soc. Y.-b.," 1£63, p. 205. 334 REMEDIES. laxation of the contracted cei'ebral arteries, and allowing free blood- flow to take place through the brain. It should, therefore, not be administered indiscriminately, not if the head was flushed and hot, and the eyes injected. Beneke^ and Clemens^ agree that the general eS"ects of baths de- pend upon their action on the nerves of the skin. The latter finds that simple or medicated baths always produce their greatest diuretic eifect in the first fifteen or twenty minutes; he could detect none of the substances dissolved in the bath water in the urine. The diu- retic eff"ect was marked, especially in increasing the flow of water, and the excretion of phosphates and other fixed salts. The chloride of sodium and urea were not much increased. Beneke lays stress on the importance of the stimulus of the bath being appropriate to the state of the system ; if it is, it causes a general sensation of well- being, a bodily and mental exhilaration, some increased frequency of pulse, and generally and as an ultimate result an increase of nutrition, and of the weight of the body. If, however, the stimulus is not suitable to the individual, these beneficial effects are replaced by shivering, lassitude, febricitation, restlessness, and loss of weight. The special advantage of the warm bath consists in the circum- stance that a very large sensory surface is mildly and equably stim- ulated, so that all the cerebral and spinal centres are moderately excited. It is on this principle that such baths as those of Gastein and Wildbad, scarcely more than hot water, act efficiently in cases of paralysis of exhaustion. This is the primary and beneficial effect, but if the temperature be too high, or the bathing too prolonged, we then have debility and nerve exhaustion produced, which may even cause a degree of syncope, such as is not uncommon to novices at a Turkish bath. The same influence which relaxes the internal arteries, and thus promotes more free circulation through the brain and cord, if carried too far, or used in too weakly a system, depresses the action of the heart, sometimes even seriously. Similar views seem to me very applicable to various medicated baths of ascertained efficacy in different neuroses. Thus sulphuret of potassium baths are certainly useful in chorea, in lead paralysis, in some cases of asthma, and in some of eczema. It is difficult to believe that the remdy can act by removing the causes of these dis- orders, while it is certain that it must exert an influence on the cutaneous nerves, which, communicated to the centres, may there effect changes which materially modify the morbid phenomena. In the following instance mentioned to me by Dr. Tyler Smith the nitro-muriatic acid lotion appears to act in a way which can only be explained by the view that certain nerves of the parietes exert an influence on those of the contained viscera. A lady whose liver is habitually torpid always gets a well-coloured bilious motion from the 1 Schmidt's " Jahrb.," vol. cxv. p. 101. 2 "iMed. Centr. Ztg.," xxx 53, 59^ 1861. REMEDIES. 335 application of spongio-piline, saturated with nitro-muriatic acid lotion, to the right hypochondrium, but a foot-bath of the same has no effect. In appropriate cases, such as are not suffering under active dis- ease, there is no calmative which is more effectual than an atmos- phere and climate suited to the state of the system. In asthma, in chronic sleeplessness, and in a variety of obscure nervous disorders change to a pure and suitable air may be of far more value to the sufferer than any drug, or mode of treatment. This is eminently the case in removal from London to the country. The cessation of the unending hum and clatter of London traffic, the perceptible stillness, affects the brain with a pleasant sense of rest, and con- tributes materially to the beneficial effect of the air. A judicious selection of locality is, however, most important. The atmosphere ■which tones, braces, and calms one system will injuriously affecj? another, and the moist relaxing air of our southern and western coasts which may calm a highly excitable, tensely nerved system will seriously depress one of an opposite quality. For many invalids convalescent, or semi-convalescent from tropical disease the Scottish moors and mountains is, I believe, preferable to any in our island. Were I similarly affected I should wish to betake myself to the Swiss Alps, avoiding, however, absolutely the close valleys, which are often most pernicious. I would say to every traveller in search of health, consider well where you make even a brief stay, for a night or two in a locality where the aspect of the population tells of malaria may infect you with a taint which it may be hard to shake off, even if no worse occur. I shall not as long as I live forget the scene that I wit- nessed at Martigny during the day I halted there. A week of illness spent there, commencing apparently in a mere diarrhoea, bereft a young affectionate wife of her husband, and left her to finish in grief the journey which had begun so joyously. In some cases frequent change is more efficacious than a continued residence in any one locality. This applies very much to the slight teasing febrile affec- tions which hang about some who have previously suffered with malarious fevers. For those who are tolerable sailors sea voyaging under favourable circumstances is one of the best restoratives. To many Indian invalids the long sea voyage would I am satisfied be safer and more health-promoting than the over-land route. APPENDIX. The subject of inhibitory paralysis appears to me to be one of so much importance that I am desirous of entering]; into it somewhat further than I have done in the text. The following are, I think, interesting examples of this morbid state. Mr. Tyrrell relates the following history.* "I was requested to see a young gentleman, set. 13, who had been suffering for many days from headache of severe kind, giddiness, flushed state of counte- nance, and great restlessness and irritability; he was also intolerant of light, and his vision was very imperfect, being obscured by a gauze or web. I found the pulse rapid, small, but very compressible; the skin dry and hot; and the tongue loaded on the median part by a thick light brown deposit, the edges being unusually red ; the appearance of this organ induced me to direct my inquiries into the state of the secretions from the alimentary canal, and to examine the abdomen ; I then learnt that the patient had been freely purged, principally by saline medicines ; but that the remedies had been dii'ected to the head, under the supposition that it was the seat of the mor- bid action ; my examination of the abdomen discovered an irregular, indu- rated swelling in the right iliac region, which I considered to result from a collection of hardened feces in the caput coli. A full dose of scammony and calomel was administered and produced a very copious discharge of hard scybala ; the relief was immediate; all urgent symptoms subsided, and after a second dose he became convalescent — proving that all disturbance, cerebral, ocular, or other emanated from the accumulation of scybala in the colon." Tyrrell adds that such cases are rare in adults, but frequent in children or young persons. Mackenzie^ relates the case of a girl, set. 7, whose vision became dim after an attack of inflammation of the eyes attended with head- ache, when suddenly her pupils became widely dilated and immovable. The abdomen was much swollen. About a month previously to this she had passed a lumbricus. After repeated doses of castor oil and turpentine she passed at diff"erent times nine lumbrici, and vomited two; after which the belly became soft, the pupils contracted when the eyes were exposed to the light, and in the course of a few months' treatment vision was restored. Dr. Burgess^ gives the history of a coloured man, set. 39, who suddenly began to sufl'er severe pain through the right eye, and over the right side of the face and head, and about this time discovered that he had paralysis of the right side of the face. The pain continuing most severe through the globe of the right eye he soon began to experience a cloudiness of vision. For the first few days all objects viewed with the right eye alone seemed of a bright yellow colour ; at the end of five or six weeks the power of vision was entirely obscured. Now began a similar set of symptoms in the left eye, resulting finally in total loss of sight in this eye also. This condition was ' Vol. ii. p 280. 2 ''On Dis. of the Eyes," p. 1061. « "Brit. Med J.," June 14tli, 1862. 23 338 APPENDIX. reached in about four months after the first attack. Two months later the eyes had a staring vacant aspect, the globes being prominent, as if pushed for- wards, the pupils largely dilated, and but little sensitive to light. No evi- dences of disease in the external coats of the eye; the deeper portions "pre- sented a greenish colour. Paralysis of the muscles of the right side of the face v?ith partial paralysis of the tongue still existed; and pain similar in character, though much less severe than that which had ushered in the dis- ease, still continued. He also described a sensation as of something crawl- ing about on the top of his brain. He had chancre four years before, but had never suffered from any consecutive symptoms. Shortly after this he was delivered from a taenia nineteen feet long by means of pumpkin-seeds and castor oil and turpentine. Two or three days after this he began to distinguish shadowy outlines of objects around him, and from this time the haze cleared away so rapidly that in a week more he was able to recognize his acquaintances. At this time the power of vision was returning only to the right eye, but soon after the left improved also. At the end of thirty days the patient could read newspapers, the pain had nearly disappeared, and both eyes had a perfectly normal appearance, save the glaucomatous hue of the inner chambers, which still existed. Paralysis continued, but was less evident. Two years and a half later the patient's sight still remained unim- paired, or nearly so, and the paralytic effects had all disappeared. Remarks. — In the first of these cases there were signs of cerebral con- gestion, of retinitis, and general pyrexia ; in the second, there was headache^ paralysis of the ciliary nerves, and ophthalmia; in the third, pain in the head and face, paralysis of the facial and hypoglossal nerves, and retinitis lead- ing to amaurosis. In all the phenomena were evidently dependent on remote irritation. The natural reading of the phenomena seems to me to be — in the first, paralysis of the vaso-motor nerves of the retinal, facial, and cerebral arteries ; in the second, cerebral neuralgia, and inhibitory palsy of the ciliary branches furnished by the third pair and of the vaso-motor nerves of the eyes; in the third, similar but more extensive neuralgia and palsy, the latter involving also both retinal vaso-motor nerves. If any one should contend that the condition in the first case was not one of vaso-motor nerve paralysis, but of direct cerebral and retinal irritation, which I can hardly think is possible, this will not apply to the second case where there was paralysis of ciliary nerves along with the ophthalmia, and still le,ss to the third where there was palsy of the right facial and hypoglossal together with retinitis. If the retinae were directly irritated the origins of these nerves should have been so too, and there should have occurred contraction rather than paralysis. In the cases quoted from Scanzoni, at p. 462, it seems impossible to believe that the cutaneous hyperaemia was the result of attraction of blood to the skin excited by reflex irritation. It would be as reasonable to regard blush- ing as the result of cutaneous irritation. Tissue irritation, as when produced by a mustard poultice, is always attended with more permanent phenomena than those resulting from arterial dilatation. The diffuse character of the inhibitory vaso-motor paralysis is very apparent in the first case, and it is worth observing that both eyes were affected in all the three. If spasm of the vessels in the centres had been the cause of the palsy in the third case, should not the retinal vessels have been in a similar condition, and would not, moreover, the long period during which the nutrition of the centres was arrested have produced softening and irreparable damage ? Dr. Brown- Sequard asserts that an inflammation cannot be explained by a hypersemia APPENDIX. 339 c rom vaso-motor nerve paralysis, but, as I have before stated, my own ex- perience quite coincides with Bernard's, that in weakly or sickly animals actual inflammation may be produced by division of the sympathetic. This conclusion seems to me quite borne out by the evidence of the above cases. No. 55 may also be cited as a proof that long-continued hyperaemia from relaxed arteries may pass into destructive pus-generating inflammation. While, however, I think that inhibitory paralysis of musculo-motor, and of vaso-motor nerves is not an infrequent form of disorder, and that the latter often gives rise to inflammation of a more or less diffuse kind, I also think there is evidence that nerve pain or nerve palsy may cause nutritional changes of inflammatory character. Herpes Zoster is an oft-quoted instance. Graves relates a case (Dublin Med. J., vol. iii. p. 342) where a gentleman, aet. 68, had an attack of hemicrania affecting the right side. Each hair felt like a minute poniard implanted in the skin, causing intense agony; at last a minute pustule that soon desiccated appeared around each hair, and in a few days his scalp got well. During the height of the disease the engaged half of the scalp was red, but not erysipelatous. The hair did not fall off. Samuel's experiments, if confirmed, prove that severe irritation of sensory and compound nerves may cause violent inflammation. He states^ that irri- tation of the tissue in the vicinity of the sciatic nerve produced healthy suppuration along the course of the nerye and its divisions, but did not ex- tend to the lower part of the leg and foot. The skin and the muscles were not inflamed. Prolonged irritation of the sciatic nerve on the contrary caused prodigious swelling and inflammation of the whole limb, with offensive sanious exudation and discoloration of the muscles. Irritation of the pos- terior spinal nerve roots and their ganglia in the lumbar region caused great swelling and hypersemia of the leg and thigh. It does not appear to me quite certain whether in these experiments the irritation was not so great as to paralyze the vaso-motor nerves, at the same time that by its action on the sensory it impaired the nutrition of the tissues. Hutchinson's cases show that small whitlows may form on the fingers in consequence of their being deprived of sensation. As counter-evidence to Samuel's experiments we ought to consider the numerous instances in which severe pain is pro- duced either by direct or reflected irritation of sensory nerves, yet without any inflammation ensuing in the part to which the pain is referred. Such instances are so numerous that it is needless to cite any at length, and I ■will only allude to two cases mentioned by Sir B. Brodie {Local Nervous Disorders, pp. 4, 5), to three cases mentioned by Romberg (vol. i. p. 72, 7o), and to an interesting case given by Dr. Churchill (Dis. of Women, p. 25.3) in which uterine cancer gave rise to no other pain except excruciating sciatica. In none of these was the nerve irritation attended with any inflam- mation. Neither was it in Denmark's'^ case where a fragment of lead im- pacted in the radial nerve caused such suffering in the hand that amputation was had recourse to, nor in a case given by Sir Charles Bell,^ where a "man died of agonizing burning pain in the sole of his foot, and the poisonous drugs that were administered in hope of relieving him. Only two days before his death I found a hard tumour like a piece of bone in the ham, and that the pain in the foot proceeded from this." After death the popliteal ' Canst.

It is true that there was an excoriation in the palm, but the skin here is supplied by the median nerve. 3 "Nervous System," 1836, p 370. 340 APPENDIX. nerve was found involved in a soft cancerous mass. In most cases vrhere neuralgic pain is attended with some degree of inflammation this evidently depends on vaso-motor paralysis and not on tissue irritation. This appears from the diffuse hypersemia, the throbbing, the paroxysmal aggravation, and especially from the cure of the whole disorder by tonics. Brodie especially mentions that inflammation produced by nerve irritation is not very active, is not such as will end in suppuration, or abscess. In Mr. Paget's case where urethral irritation caused abscess in one testis we need more exact in- formation respecting the state of things during the time that the abscess was forming. It does not seem to me fully proved that the morbid action was not communicated by continuity of tissue. This is the explanation which Dr. Mackenzie is most inclined to adopt with regard to sympathetic ophthal- mitis. He says : " It is extremely probable that the retina of the injured eye is in a state of inflammation, which is propagated along the correspond- ing optic nerve to the chiasma, and that thence the irritation which gives rise to inflammation is reflected to the retina of the opposite eye along its optic nej:"ve." If the view be taken that the inflammation depends on in- hibitory irritation of the nerves of the secondarily-affected eye, it should be observed that, as Dr. M. states, the subjects of sympathetic ophthalmitis are debilitated and in ill-health, and that the inflammation is unhealthy. The occurrence of purulent otorrhcea together with auriculo-temporal neuralgia is clearly an instance of vaso-motor nerve paralysis, the vasal nerves being paralytically affected like the sensory. On the whole, after comparing the teachings of science with our expe- riences in practiccj I find that the theories of vaso-motor paralysis, of in- hibitory action, and of the paralytic character of neuralgia are of great value as affording a rational basis for treatment, and as combining together in an intelligible view numerous facts which would otherwise be of little signifi- cance ; — but the doctrine of special trophic nerves seems to me at present to be but sparingly applicable to the phenomena of disease. One of its principal supporters (Samuel) regards fever and inflammation as states of excitement of the trophic nerves, and atrophies as the reverse. Now certainly the view which Bernard's observations lead to as regards fever and many cases of inflammation is much more consonant with experience. The essential idea of the inhibitory theory is that a peculiar kind of im- pression made on a centre may disorder or paralyze its action, may prove directly depressing. There seems to be ground for believing that such im- pressions may be generated within the cranial cavity as well as at the pe- riphery. The crossed paralysis resulting from hemorrhage into one hemis- phere of the cerebellum seems only explicable on the view originally pro- pounded by Mayo that the fibres of the transverse commissure coming from the diseased side communicate "a depressing" or "withering influence" to the descending fibres conducting voluntary motor impulses. Perhaps it may be more correct to regard all the fibres uniting together nervous centres as wholly commissural, and to consider the morbid influence in this case there- fore as affecting the gray matter of the pons Varolii rather than the fibres, but this is only a slight modification of the original view. One circum- stance which seems to support it is that the crossed paralysis only occurs, according to Hillairet,* in about one-third of all the cases ; — the reason being, that in the other two-thirds the morbid impression is either ihsuflicient * "Ann. de Med. et de Chir. pratiq. par Jamain," 1859, p. 39. APPENDIX. 341 to overcome the volitional impulse, or takes another direction, as to the corpora quadrigemina, causing blindness or convulsions, or to the medulla oblongata impairing respiration or speech, or even to the lower part of the cord producing predominating paraplegia. The non-occurrence of para- lysis in some cases of disease of the cerebrum itself is probably to be ex- plained in the same way. It is not the lesion of the hemisphere per se that causes the paralysis, but the depressing influence of this lesion on the deeper- seated cerebral ganglia. Paralysis therefore may or may not exist according to the quality of the nervous power, or the peculiar kind of lesion. In cer- tain instances, as Dr. Ogle^ has pointed out, the morbid influence may take another route and act on the cerebral ganglia of the opposite side so that the paralysis affects the limbs on the same side as the lesion. This view may afford some rational ground for treatment in cases which would otherwise be hopeless. It is true that we may be unable to amend materially the state of the damaged part, but we jnay be able so to improve the functional power of a connected centre that it shall not be depressed by the " withering influence" conveyed to it from the seat of the lesion. ' ^'Med.-Chir. Trans.," vol. 42. YINDEMIATIO. (1.) In all cases we should be guided as to treatment by the pathological condition existing much more than by the name of a disease. Morbid con- ditions called by the same name may be utterly different essentially, and ' require most different management. We should always endeavour to esti- mate the quality and amount of the nervous power. (2.) The same cause may give rise to very various and even apparently opposite effects, according to the state of the nerve or nervous centre on which it acts ; thus an irritation may either paralyze a muscle, or throw it into convulsion or into rigid spasm ; may cause pain or numbness or local tenderness; may produce cerebral excitement or depression. Much depends on the degree of irritation, a moderate may excite, while a powerful may depress. The same may be said of the kind or quality of the irritation, an appropriate kind stimulates, while one which disagrees has an opposite effect. (3.) The result of a stimulant or of a sedative may be different according as it affects the cerebro-spinal or vaso-motor nerves. The constriction of the arteries produced by the action of a stimulant on the latter may diminish or temporarily arrest functional power, and vice verm dilatation of arteries produced by a sedative may give rise to excessive action. The operation of these agents on the cerebro-spinal nerves or centres is just the reverse. (4.) Hyperaemia from paralysis of vaso-motor nerves is very common, and may under conditions of general exhaustion or local irritation pass on into actual and complete inflammation. This hyperaemia or inflammation is always diffuse. (5.) We should bear in mind the frequent occurrence of reflex inhibitory action, implying the paralysis of cerebro-spinal or sympathetic nerves, as the result of a stimulus morbid in kind or degree in relation to the centre on which it acts. Such morbid impressions may originate within the cranium from lesion of the membranes or of a nervous centre. (6.) Debility and excitability of nervous centres and nerves very often increase pari passu, but the former may exist alone. When very great it constitutes what may be termed simple paralysis, a simple loss of functional power. This is specially distinguished from reflex paralysis by being amenable to repose, generous diet and tonics, while reflex requires the re- moval of the exciting cause. Simple paralysis of a nervous centre much more often affects motion than sensation. It occurs both in the spinal and encephalic districts, (7.) Paresis of nervous centres constitutes the primary and essential part of the affection termed sunstroke or heat-apoplexy ; the vascular congestions being induced secondarily and depending in great measure on loss of tone iu the capillaries and small arteries. According to this view the intimate rela- 344 VINDEMIATIO. tion between such disorders and various forms of fever is easily intelligible, as vaso-motor paresis seems to constitute an essential part of all febrile movement. (8.) Active cerebral excitement may be either of a sthenic, an asthenic, or a medium quality, and will require corresponding modifications of treatment, and this independently of the nature of its exciting cause. This entirely applies to delirium tremens. (9.) Spinal excitement (tetanus) is to be regarded more as a dynamic than a toxic affection. Its affinity to paralysis, and its relation to prostrating influences, as prolonged heat and cold and wet, should be borne in mind. Catalepsy, a variety of tetanus, is sometimes produced by exhaustion. (10.) The epileptic paroxysm is immediately dependent on spasm of all the encephalic arteries in the greater, and those of the hemispheres only in the minor form. Sudden temporary aDseraia is thus the necessary condition of the occasional paroxysm, but in prolonged convulsions, as puerperal, ex- an thematic, of tubercular or of uraemic origin, it is probable there is direct irritation of the tubercular quadi'igemina and adjacent parts with more or less secondary hypergemia. The latter when primary may no doubt be a predisposing, but if it stop short of actual inflammation, is scarcely ever an exciting cause of convulsions. Hyperaesthesia of the excitable districts, quite analogous to that affecting peripheral nerves, is, however it may be excited, the fundamental cause of convulsions. According to the quality of this hypersesthesia counter-irritants, sedatives, or tonics, or a combination of. them may be requisite. (11.) Chorea is in most cases a dynamic disorder of debility, involving a greater or less extent of the cerebro-spinal centres, sometimes only the motor apparatus, sometimes the hemispheres also. Paralysis agitans, when not of organic origin, is a similar but more limited affection involving some part of the spinal centres. (12.) Muscular spasms and contractions are attributable to disorder of motor nerves similar to the neuralgia of seiisory, and like them are some- times of central sometimes of peripheral origin. They may also be of sthenic or asthenic quality. A series of gradations may be traced from tonic spasms, through clonic tremors, and choreic agitation to actual paralysis. (13.) Wherever nerves exist neuralgic affections may and do occur. As to their quality they may present either that of hypersesthesia where ten- derness and excitement predominate and sedatives relieve, or that of neu- ralgia characterized by pain and depression, and relieved by stimulants. These are the typical forms, but of course intermediate and mixed ones are most common. As to their origin they are in most cases intimately con- nected with depressing agencies, or with malaria, but may be dependent on remote irritation, or gouty or syphilitic poison. (14.) Headache may be produced either by neuralgic affection of the brain itself, or of the nerves of the parietes, and may be characterized by hyperaesthesia, or by prostration. Like other nerve disorders it may be produced by direct or remote irritation. (15.) Vertigo may be produced by any sudden alteration in the state of VINDEMIATIO. 345 the cerebral circulation, or by enfeeblement of its power, or by direct or remote irritation interfering with the due action of its tissue. (16.) Angina pectoris is essentially a cardiac neuralgia, consisting as so often observed in other situations of sensory and motor disorder, pain and spasm. It may be produced by very different causes as well as other cardiac neuroses. (17.) The fatal termination of laryngismus stridulus probably depends on cardiac spasm associated with the glottic. (18.) The convulsions attending on pertussis and other severe coughs do not depend on hyperfemia of the brain, but on propagation of the motor dis- order to the nerves of the cerebral vessels. (19.) Hemorrhages to a greater or less amount may result from causes of prostration acting through the vaso- motor nerves on the small arteries and capillaries. The nerve paresis causing dilatation of the arteries flushes the parts which they supply with blood, while the same condition impairing the quality of the capillary wall allows actual blood to escape into the tissue or on a free surface. (20.) Miasmata giving rise to ague are generated occasionally in and around London. Young children are prone to sufier from a remittent fever of this kind attended with various complications. In adults it sometimes shows itself in a very obscure form attended with great nervous prostration and depression. (21.) In well-marked cases of hysterical disorder (so called) the mind and morale may be perfectly sound and healthy. (22.) Remember the distinction between the radical and the acting forces, V. p. 216. (23.) In treatment large allowance must be made for idiosyncrasy; the kind of remedy may be clearly enough indicated, but it may not be easy to determine the particular one required. It is also essential to ascertain the proper dose; a remedy may fail because given in too large or too small an amount, or because it has not been given for a- sufficient length of time. II^DEX.
